In a uniform electric field, the potential is ` 10V` 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`
