Physics Question on electrostatic potential and capacitance
The electric potential on the hollow sphere ofradius 1 m is 1000 V. The potential at 41 m from the centre of sphere is
A
1000 V
B
500 V
C
250 V
D
zero
Answer
1000 V
Explanation
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.
