Consider a uniformly charged solid cube of side 'a' and volume charge densityρ . The centre of cube is O and one of vertex is A.

Question 1

Consider a uniformly charged solid cube of side 'a' and volume charge densityρ .The centre of cube is O and one of vertex is A. The potential at one of the vertex is given by Where c is a dimensionless constant. Select correct alternatives

(A) x = 1

(B) y = 2

Question 2

Correct option: (A, B, C)

Explanation:

Dimensionaly

comparing both sides x = 1, y = 2

cube of side a can be assumed to be madeup of eight small cubes of side a/2.

If VA is potential at vertex of big cube then potential at vertex of small cube will be VA/4 so net potential of centre VO = 8 VA /4
