Question
A positive point charge Q is kept (as shown in the figure) inside a neutral conducting shell whose centre is at C. An external uniform electric field E is applied. Then :
Options
A.Force on Q due to E is zero
B.Net force on Q is zero
C.Net force acting on Q and conducting shell considered as a system is zero
D.Net force acting on the shell due to E is zero.
Solution
Force on Q due to E is QE. and not zero. Force on Q is zero due to E & electric field of induced outer charges on sphere.
Charge density on inner surface is not uniform therefore net force on charge Q is not zero.
Due to E, net force on shell is zero because net charge on shell is zero.
Charge density on inner surface is not uniform therefore net force on charge Q is not zero.
Due to E, net force on shell is zero because net charge on shell is zero.
