A point charg...

Question

A point charge +q is moved inside a spherical shell of radius R and carrying charge Q from a point A to another point B which is diametrically opposite. Find the work in moving the charge from A to B. Give reasons

Open in App

Solution

value of Potential inside the shell Vinside = (1/4πε0)Q/r

r= distance from centre to the point

since both points are diametricaly opposite pottential at both points will be same so work done to move the charge q from one point to another is zeo
