In a field free region, two electrons are released to move on a line towards each other with velocities 106ms−110^{6}m^{s - 1}The distance of their closest approach will be nearer to.

A

1.28×10−10m10^{- 10}m

B

1.92× 10−10m10^{- 10}m

C

2.56× 10−10m10^{- 10}m

D

3.48×10−10m10^{- 10}m

Answer

1.28×10−10m10^{- 10}m

Explanation

Solution

When a point charge +q+ qis placed at a distance d from an isolated conducting plane, some negative charge develops on the surface of the plane towards the charge and an equal positive charge develops on opposite side of the plane.

Hence, the field at a point P on the other side of the plane is directed perpendicular to the plane and away from the plane as shown in figure.
