Question

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, I). The potential at the point (1, 1, 1) will be :

• A. 0
• B. 4 V
• C. 8 V
• D. 10 V

Answer 1

The correct option is B 4 V

In a uniform electric field, equal displacements cause equal changes in potential.
Each of displacements OA, AB and BP cause a drop in potential of 2 V.
Thus, the potential at P $=10-2-2-2=4$V
