Questions
Mark the correct statement:
a
An electron and a proton when released from rest in a uniform electric field experience the same force and the same acceleration.
b
Two equipotential surfaces may intersect.
c
A solid conducting sphere holds more charge than a hollow conducting sphere of the same radius.
d
No work is done in taking a positive charge from one point to another inside a negatively charged metallic sphere.
detailed solution
Correct option is D
Option (a) is wrong because force will be the same, but acceleration will be different because masses of electrons and protons are different. Option (b) is wrong because at a point there can be only one potential. Option (c) is wrong because charge always lies on the outer surface of a conductor. Option (d) is correct because the whole conductor will be an equipotential body.Talk to our academic expert!
