Assume that an electric field E =30 x ^2 i exists in space. If ' V ₀ ' is the potential at the origin and ' V _ A is the potential at x =2 ~m , then the potential difference ( V _ A - V ₀ ) is

Options

  1. A-80 ~J
  2. B-120 ~J
  3. C80 ~J
  4. D120 ~J

Correct answer

A. -80 ~J

Step-by-step solution

aligned & d V= E d x & _ V₀ ^ V_A d V=- ₀^2 30 x^2 d x & V_A-V₀=- [10 x^3 ]₀^2=-80 J aligned
