Questions
An electron of mass me initially at rest' moves through a certain distance in a uniform electric field in time t1. R proton of mass mp, also, initially at rest' takes time t2, to move through an equal distance in this uniform electric field. Neglecting the effect of gravity the ratio of t2 / t1, is nearly equal to
detailed solution
Correct option is B
For electrons=eEMe×t12For Proton s=eEmp×t22∴ t22t12=mpme or t2t1=mpmeTalk to our academic expert!
