AN isolated conducting sphere whose radius R is 6.85 cm has a charge q=1.25 nC (a) How much potential energy is stored in the electric field of this charged conductor? (b) What is the energy density at the surface of the sphere?
What is the radius of the imaginary concentric sphere that divides the electrostatic field of a metal sphere of a radius 20 cm and change of 8muC in two regions of identical energy?
In the above problem, find the electric field and electric potential at the centre of the sphere due to induced charges on the sphere?
The electric field due to a point charge at a distance R from it is E. If the same charge is placed on a metallic sphere of radius R , the electric field on the surface of the sphere will be nE , then the value of n is
A spherical charged conductor has sigma as the surface density of charge. The electric field on its surface is E. If the radius of the sphere is doubled keeping the surface density of charge unchanged, what will be the electric field on the surface of the new sphere -
