Question

Consider a solid sphere of radius 5 cm made of a perfect electric conductor. If one million electrons are added to this sphere, these electrons will be distributed

• A. uniformly over the entire volume of the sphere.
• B. uniformly over the outer suface of the sphere.
• C. concentrated around the centre of the sphere
• D. along a straight line passing through the centre of the sphere.
