Question

Charge on a conducting metal sphere present at:
(a) On the surface of sphere
(b) Inside the sphere
(c) Outside the sphere
(d) both inside and outside of sphere

Answer 1

Answer:

(a)

Explanation:

Answer 2

The charge on a conducting metal sphere is present on the surface of the sphere.

Explanation:

• Conductors are considered to be ideal in electrostatics.
• Thus free mobility inside the conducting metal sphere is assumed.
• The electric field is zero, inside a conducting metal sphere,
• On applying Gauss' law on a conducting metal sphere,
• when the radius taken into consideration is smaller than a radius of the conducting metal sphere, the net charge inside it is zero.
• This leads to the conclusion that all the charges of the conducting metal sphere lie on the surface of the conducting metal sphere.

Thus, the correct option is (a).
