प्रश्न
Two large conducting spheres carrying charges Q1 and Q2 are brought close to each other. Is the magnitude of the electrostatic force between them exactly given by Q1 Q2/4π∈0r 2, where r is the distance between their centres?
उत्तर
The force between two conducting spheres is not exactly given by the expression, Q1 Q2/4π∈0r 2, because there is a non-uniform charge distribution on the spheres.

In a Van de Graaff type generator a spherical metal shell is to be a 15 × 106 V electrode. The dielectric strength of the gas surrounding the electrode is 5 × 107 Vm−1. What is the minimum radius of the spherical shell required? (You will learn from this exercise why one cannot build an electrostatic generator using a very small shell which requires a small charge to acquire a high potential.)
A small sphere of radius r1 and charge q1 is enclosed by a spherical shell of radius r2 and charge q2. Show that if q1 is positive, charge will necessarily flow from the sphere to the shell (when the two are connected by a wire) no matter what the charge q2 on the shell is.

An electric dipole has a fixed dipole moment `vec "p"`, which makes angle `theta` with respect to x-axis. When subjected to an electric field `vec"E"_1 = "E"hat"i"`, it experiences a torque `vec "T"_1 = tau hat"k"`.
