A) V
B) 2V
C) 4V
D) -IV
Correct Answer: A
Solution :
The electric field between the spheres depends only on the charge of the inner sphere. So, in conformance with the relation \[dV=-\int_{{}}^{{}}{\vec{E}.\overrightarrow{dr}}\]the potential difference between the spheres depends only on the charge of the inner sphere. So, even if the charge of the shell is changed to -3Q, the sought potential difference remains same as before. Hence, the correction option is [a].You need to login to perform this action.
