A) \[+Q\],\[-Q\], \[0\]
B) \[Q\], \[+Q\], \[0\]
C) \[0\],\[-Q\], \[0\]
D) \[+Q\], \[0\], \[0\]
Correct Answer: B
Solution :
The solid conductor with a cavity is shown in figure. The inner surface of cavity will be \[-Q\] due to induction. At outer surface, the charge will be \[+Q\] and at a point between P at a position \[r(a<r<R)\]will be zero.You need to login to perform this action.
