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
Dear Student
Suppose the radius of inner shell=r
Radius of outer shell=R
Charge on the inner shell=q
Charge on the outer shell=q'
For the inner shell,
V=kq/r +kq'/R
For any point x<r,
V=kq/r +kq'/R (Same as for inner shell)
Thus,
Potential at centre of shell=Potential of inner shell=10V
