Question

3. Three bodies- a sphere, a cube and a cone are made to develop charge, then
(a) uniform charge distribution takes place in the spherical body only.
(b) uniform charge distribution takes place in the cubical body only.
(c) uniform charge distribution takes place in the conical body only.
(d) all the three bodies attains uniform charge distribution.
(Kindly provide reasons)​

Answer 1

Given:

Three bodies- a sphere, a cube and a cone are made to develop charge.

To find:

The body acquires uniform distribution of charge.

Concept:

It is a property of charges that they tend to to occupy the maximum surface area in a uniform manner on any conductor in order to stay stable.

So, if we develop charge Q on the spherical, cubical and conical objects (considering them to be hollow), the charges shall re-establish themselves along the maximum surface area possible for each of the objects and it will be present uniformly along the surface.

Hence we will observe uniform distribution of charge in all the three bodies (i.e. spherical, cubical and conical).

Hence , Correct Option is D
