Question

Need help with drawing a force diagram for part (b) of this problemplease.
An electron starting from rest acquires 6.3keV of KE in movingfrom point A to point B. (a) How much KE would a proton acquire,starting from rest at B and moving to point A? (b) Determine theratio of their speeds at the end of their respectivetrajectories.

Explanation / Answer

(b)    as the motion is a straight line motionthere will not be a necessary diagram to get    the ratios will be    (1 / 2) mpvp2 = (1 / 2) meve2    ve / vp =(mp / me)              =[(1.67 x 10-27 kg) / (9.11 x 10-31kg)]             = ........    ve / vp =(mp / me)              =[(1.67 x 10-27 kg) / (9.11 x 10-31kg)]             = ........
