A green ball weighs 75 g and comes travelling towards you at 400 cm/sec speed. A photon of light emitted from the green ball has a wavelength of 5*10^-5 cm. Assuming that the error in position of ball is same as its own wavelength, calculate the error in the momentum of the ball ?

0.5*10^-23 1.055*10^-23 1 2.3*10^-23
