Laws of Motion doubt!

Thank you for your precious time!

#Mechanics

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.

the first option is correct.its quite easy as ma is constant since the horizontal components of the forces(normal reaction) are equal So the accelerations get divided inversely as masses.

Is your course at fiitjee completed?

A Former Brilliant Member - 4 years, 4 months ago

Could you please explain why the horizontal components are equal?

Swapnil Das - 4 years, 3 months ago

Note that its nothing but the x components of the normal reactions that we talking abt.they must be equal.

Spandan Senapati - 4 years, 3 months ago

Thanks.!! I was thinking about this ,but could not believe that I the question could be so simple. BTW you physics is awesome!!

A Former Brilliant Member - 4 years, 4 months ago

is it ok now ? i mean you understood , right ?

A Former Brilliant Member - 4 years, 4 months ago

@A Former Brilliant Member – Yes ,thanks for reply!!!

A Former Brilliant Member - 4 years, 4 months ago

Ya its complete.12 th course has started as well.??wbu??you are in which centre??

Spandan Senapati - 4 years, 4 months ago

@Spandan Senapati – Well I am from bhilai( chhattisgarh) centre.we are way too back,thermodynamics in physics is going on and hydrocarbons in Chem

A Former Brilliant Member - 4 years, 4 months ago

@Spandan Senapati – Hello! Are you from Bhubaneswar centre?

Swapnil Das - 4 years, 3 months ago

@Swapnil Das – Yes!!and you seem to be from odisha as your tagline says.are you??

Spandan Senapati - 4 years, 3 months ago

@Spandan Senapati – Yes, Indeed. And I got the answer to my question by a FBD, thanks :)

Swapnil Das - 4 years, 3 months ago

@Swapnil Das – Which class??

Spandan Senapati - 4 years, 3 months ago

@Spandan Senapati – Going to be 11th this year. BTW, did you qualify NSEP and NSEA in 11th?

Swapnil Das - 4 years, 3 months ago

@Swapnil Das – Yes☺☺

Spandan Senapati - 4 years, 3 months ago

@Spandan Senapati and @A E

Should we make a physics doubt board?

Swapnil Das - 4 years, 3 months ago

Ok go on☺☺

Spandan Senapati - 4 years, 3 months ago

Btw, please try this problem. (https://brilliant.org/problems/wedge-problem/?ref_id=1327438)[Link] . Is the answer correct?

Swapnil Das - 4 years, 3 months ago

@Swapnil Das – Oh I got the and as 20/3.entered 6.67.didn't accept.report it.

Spandan Senapati - 4 years, 3 months ago

@Spandan Senapati – 20/3 is correct.

Spandan Senapati - 4 years, 3 months ago

@Spandan Senapati – yes got the same... lets report!!!!

A Former Brilliant Member - 4 years, 3 months ago

Yeah.... go ahead
