An electron of mass m initially at rest moves through a certain distance in a uniform electric field in time 1 A proton of mass m also initially at rest takes time t to move through an equal distance in this uniform electric field Neglecting the effect of gravity the ratio t t is nearly equal to A I C m m B m m 2 D 1836 An electron is projected as in figure with kinetic energy K at an angle 0 45 between two charged plates The magnitude of the electric field so that the electron just fails to strike the upper plate should be greater than
