Question
Potential at a point x is 5 V and at a point y is -5V. A proton is moving towards x from y, then
Options
A.It must have K.E. more than 10 eV to reach x from y
B.Work done by 
in motion from x to y is + 10 eV
in motion from x to y is + 10 eVC.work done by in motion from y to x is zero
in motion from y to x is zeroD.K.E. at y is more than K.E. at x, if particle is released at x.
