The electric field in a region of space is given as E = (5 NC ⁻¹ ) x i . Consider point A on the Y -axis at y=5 ~m and point B on the X -axis at x=2 ~m . If the potentials at points A and B are V_A and V_B respectively, then (V_B-V_A ) is

Options

  1. A-15 ~V
  2. B8 ~V
  3. C-10 ~V
  4. D-12.5 ~V

Correct answer

C. -10 ~V

Step-by-step solution

The given situation is shown below Since, electric field is directed along the X - axis, hence, point A and C lie on equipotential surface Potential at point C= Potential at point A V_C=V_A V_B-V_A=V_B-V_C=-E x=-5(2-0)=-10 ~V
