Question

Identical charges (–q) are placed at each corner

of a cube of side 'b' then electrical potential

energy of charge (+q) which is placed at centre

of cube will be?​

Answer 1

Answer:

Explanation:

identical charges (-q) are placed at each corner of a cube of side b, then electric potential energy of charge (+q) which is palced at centre of the cube will be. Solution : Length of the diagonal of a cube having each side b is √3b. So distance of centre of cube from each vertex is √3b2.
