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 ......$volt$

A

$10$

B

$5$

C

$15$

D

$0$

Solution

$K\left(\frac{q_{1}}{b}+\frac{q_{2}}{a}\right)=10 v K\left(\frac{q_{1}}{b}+\frac{q_{2}}{a}\right)=5 v K\left(\frac{q_{1}+q_{2}}{b}\right)=?$ clearly

$V_{c}=10 V$
