Question

The electrostatic potential on the surface of a charged conducting sphere is 100V. Two statements are made in this regard: S1 : At any point inside the sphere, electric intensity is zero. S2 : At any point inside the sphere, the electrostatic potential is 100V. Which of the following is a correct statement?

2 points

S1 is true but S2 is false.

Both S1 & S2 are false.

S1 is true, S2 is also true and S1 is the cause of S2.

S1 is true, S2 is also true but the statements are independant.

​

Answer 1

S1 is true, S2 is also true and S1 is the cause of S2

Option (C) is correct.

Explanation:

• The relation between electric intensity E and electric potential V is given by:
• E = dV / dr
• If electric field intensity is zero "0" then dV / dr is also zero.
• As E = 0 then the Electrostatic potential at any point inside the sphere will be 100 V.
• Also remember that is the electric filed inside the charged sphere is zero it doe s not necessarily mean that the electric potential is also zero.
