Dear student

the dipole moment p induced in an atom of neon gas whe an electric field E is applied. , is

P = $\alpha$ $\varepsilon$ o E

P = np = $\varepsilon$ o(K –1)E

p = $\varepsilon$ o (K –1)E / N

the volume of 1 m atoms of neon at N.T.P. is 22.4 litres.

N = Na / V

Hence on calculation

p = 2.65 * 10 ^ –36 Cm

Three identical balls are placed on a frictionless horizontal surface touching each other. They stick to each other because of adhesive. Another ball of same radius and mass m is placed over the void created by the three balls. Find the forces applied by the balls kept on the floor to each other if the system remains in equilibrium.
