Homework Statement
I have a simple question.
There is positive point charge in the center of a sphere 2.5 micro c. The spherical shell has inner radius of 60 cm and outer radius of 90 cm. The net charge of the spherical shell is equal to zero.
Homework Equations
The Attempt at a Solution
Now the net charge = 0 :
Does this mean the 2.5 + charge on the inner radius + charge on the outer radius = 0?
Because that's what I did while solving the problem.
which gave me Charge on inner radius = -2.5 and charge on outer radius = 0
But the solution manual says that charge on the inner radius + charge on the outer radius = 0
which means Charge on inner radius = -2.5 and charge on outer radius = +2.5
