A particle of mass 2 g and charge 
is held at rest on a frictionless horizontal surface at a distance of 1 m from a fixed charge of 1 mC. If the particle is released, it will be repelled. The speed of the particle when it is at distance of 10 m from the fixed charge is:
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
