Q.
The electric potential on the hollow sphere ofradius 1 m is 1000 V. The potential at $\frac{1}{4}$ m from the centre of sphere is
MP PMTMP PMT 2010Electrostatic Potential and Capacitance
Solution:
Inside the conducting charged sphere eiectric field is zero and potential remaines constant at all points and equals to potential at the surface.
Hence, the potential at I /4 m from the centre is 1000 V.
