Electrostatics Question 247

Question: There is a uniform electric field of strength 103V/m along y-axis. A body of mass 1g and charge 106C is projected into the field from origin along the positive x-axis with a velocity 10m/s. Its speed in m/s after 10s is (Neglect gravitation) [EAMCET 2001]

Options:

A) |E1|=|E2|, V1=V2

B) E1E2, V1V2

C) E1E2, V1=V2

D) |E1|=|E2|, V1V2

Show Answer

Answer:

Correct Answer: D

Solution:

Outside the charged sphere, (for equal distances from centre) if electric fields at two points are same then both points must be equipotential points.
