Question
A charge Q is kept at the centre of a conducting sphere of inner radius R1 and outer radius R2. A point charge q is kept at a distance r (> R2) from the centre. If q experiences an electrostatic force 10 N then assuming that no other charges are present, electrostatic force experienced by Q will be:
Options
A.− 10
B.0
C.20 N
D.none of these
Solution
Since, no external electric field can enter into a conductor so force experienced by Q = 0
