A thin spherical shell is charged by some source. The potential difference between the two points C and P (in V) shown in the figure is:
(Take \(\frac{1}{4}\pi\epsilon_0 = 9 × 109\)\(\frac{1}{4\pi\epsilon_0}=9\times10^9\) SI units)

A capacitor of capacitance C=900 pF is charged rally by 100 V battery B as shown in figure (a). Then B is disconnected from the battery and connected to another uncharged capacitor of capacitance C=900 pF as shown in figure (b). The electrostatic energy stored by the system (b)is:
Two hollow conducting spheres of radii R1 and R2 (R1 >>R2) have equal charges. The potential would be:
The electric resistance of a certain wire of iron is R. If its length and radius are both doubled then
