In a region, the electric field is (30 i +40 j ) NC ⁻¹ . If the electric potential at the origin is zero, the electric potential at the point (1 ~m , 2 ~m ) is
Options
- A-60 V
- B-75 V
- C-55 V
- D-110 V
Correct answer
D. -110 V
Step-by-step solution
E =(30 i +40 j ) N NC ⁻¹, ~V (0,0)=0 Now, d v=- E d r =-(30 i +40 j )(d x i +d y j +d z k ) aligned & _ (0,0) ^ (1,2) dv =-30 ₀^1 dx -40 ₀^2 dy & V (1,2)- V (0,0)=-30 1-40 2 & ~V (1,2)=-110 ~V aligned
