A spherical conductor is charged up to a potential of 450 V . The potential outside, at a distance 15 cm from the surface, is 300 V . Then

Options

Athe potential at 15 cm from the center is 900 V
Bthe charge on the conductor is 1.5 nC
Cthe electric field just outside the surface is $150 \mathrm{~N} / \mathrm{C}$
Dthe total electrical energy of the conductor is $U=3.375 \mu J$

Correct answer

D. the total electrical energy of the conductor is $U=3.375 \mu J$
