Question

In a uniform electric field the potential at origin is V and V/2 at each of the points (a, 0, 0), (0, b, 0) & (0, 0, c). The potential at (a, b, c) will be-

• A. $\frac{V}{2}$
• B. –$\frac{3V}{2}$
• C. –$\frac{V}{2}$
• D. – V

Answer 1

Answer: (C)

–$\frac{V}{2}$

Answer 2

= + +

dV = – E.dr

= –––

V₀ – V = –––

V₀ = V – $\frac { 3 \mathrm {~V} } { 2 }$ Ž V₀ = –
