A cube of side x has a charge q at each of its vertices. The potential due to this charge array at the centre of the cube is.
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
B
The length of diagonal of the cube of each side x is
Distance between center of cube and each vertex,
Now, potential, 
Since cube has 8 vertices and 8 charges each of value q are present there
