Four point charges are kept at the vertices of a regular tetrahedron of side R. Total electrostatic energy of the configuration is $\frac{akq ^{2}}{R}$ . The value of $α$ is :-

Answer:

Solution:

A regular tetrahedron has 6 edges, each pair of charges contributing $\frac{k q ^{2}}{R}$ .

Total energy $U = \frac{6 k q ^{2}}{R}$ , so $α = 6$ .
