Question

If the electric potential of the inner metal sphere is `10` volt & that of the outer shell is `5` volt then the potential at the centre will be

A. `10` volt
B. `5`volt
C. `15`volt
D. `0`

Answer 1

Correct Answer - A
`K(q_(1)/(b)+(q_(2))/(a))=10vK(q_(1)/(b)+(q_(2))/(a))=5v K((q_(1)+q_(2))/(b))=?` clearly `V_(c)=10V`
