In a uniform electric field, the potential is `10 V` at the origin of coordinates and 8 V at each of the points `(1,0,0), (0,1,0)` and `(0,0,1)`. The potential at the point `(1,1,1)` will be

Options

A. 0
B. 4V
C. 8V
D. 10V

Answer

B

Explanation

Here potential decreases `2V` as we moves unit distance. Hence for point (1, 1, 1) from (0, 0, 0). The total potential decrease is `2+2+2=6V`. Hence the potential at poinr will `(10-6)=4V`
