About conservation of charge

We studied that charge is conserved and mass is not conserved.suppose there is a electron with mass 9.10938291 × 10-31 kilograms and charge 1.60217657 × 10-19 coulombs.if we convert the whole the mass into energy what will happen to the charge?we have also studied that mass-less object can't carry charge.

This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.
Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.

electron is a fundamental particle with a negative charge. to convert all of electron's mass to energy, one has to react the electron with the antimatter equivalent of the electron, which is a positron. A positron carries a positive charge. as such, charge is still conserved.

is there any other method to convert electron into energy? can't we make energy,E=MeC^2(Me=mass of electron)from an electron?throw this method we get energy,E=2MeC^2

Sreehari Vp - 8 years ago

The short answer: you can't. That's the beauty of physics. In order to uphold both the conservation of charge and the energy-mass equivalence, nature is such that the electron must annihilate with another particle with the opposite charge.

@Jiahai Feng – Nice answer Jiahai F.

Shubham Srivastava - 8 years ago

@Jiahai Feng – then how energy is producing in nuclear reactors?

Sreehari Vp - 8 years ago

@Sreehari Vp – the mass of the products is less than the mass of the reactants. the nuclear equation is still balanced in terms of charge, mass number and atomic number. the mass defect is converted into energy.

Ramon Vicente Marquez - 8 years ago

charge remains intact.using the mass energy equation we do only get the energy equivalent of mass which is the all form of energy stored in the body.charge is its intrinsic property

abhay sahu - 8 years ago

Suppose somehow we did convert electron's mass into energy then what? Its theoretically possible I suppose. Is there a reason why it can't be otherwise.

Lokesh Sharma - 8 years ago

theoritically it is possible to calculate but its too less and can be ignored i guess.and the use of equivalence of mass energy is the total energy stored in the body and to use it to the fullest i guess research might be going on....and total energy just mean the potential,kinetic,nuclear,gravitational and all forms of energy engulfed within the body forming the shape of the matter....

abhay sahu - 8 years ago

i didn't get the idea.please explain......

Sreehari Vp - 8 years ago

You have said that mass less objects cannot carry charge, can you please explain why is it so?

Pratik Singhal - 8 years ago

I don't know.........but i heard it from different places

Sreehari Vp - 8 years ago

if there is charge, there must be electrons or protons, and they carry charge.

Shourya Pandey - 8 years ago

charge is carried by electrons and protons. If you convert them to energy I guess you lose charge.

Sebastian Garrido - 8 years ago

but charge is conserved.

Sreehari Vp - 8 years ago

does the body get disappear??if no then the charge will always be conserved...we just lose the mass

abhay sahu - 8 years ago

i guess if we use all the energies(mass energy equivalence) inside the body the body dismantles and its no more the mass...so is the charge!

abhay sahu - 8 years ago

I think there should be relation between mass and charge carried by the object obeying the energy conservation!!!!

Subhrodipto Basu Choudhury - 8 years ago

the charge will disappear with all the charges inside but with only a friction in the end some atomic nuclear (hypotenuse), E=mc^2 from the equation if you lose 1 gram of mass, it will create an energy greater that hiroshima nuclear bomb, the mass mostly come from neutron wich is neutral and only by losing the mass of the neutron can be converted to ''high energy density'', how about electron? the mass to given an energy is to ''small''.

Sam Alexander - 8 years ago

what is the relation of mass with charge?
