Hollow SphereElectricity and Magnetism Level pending
In a conducting hollow sphere of inner and outer radii 5 cm and 10 cm respectively, a point charge Q = 1 C is placed at point A, that is 3 cm from the centre C of the hollow sphere. An external uniform electric field of magnitude 20 N/C is also applied. Net electric force on this charge is 15 N, away from the centre of the sphere. Find magnitude of force exerted by this charge Q placed at point A on the sphere.
