The potential is varying with distance ( x ) as V = 1 2 ( y ^2-4 x ) volt. The electric field at x =1 ~m and y =1 ~m is
Options
- A2 i + j Vm ⁻¹
- B-2 i + j V m⁻¹
- C2 i - j Vm ⁻¹
- D-2 i +2 j Vm ⁻¹
Correct answer
C. 2 i - j Vm ⁻¹
Step-by-step solution
aligned & V= 1 2 (y^2-4 x ) & E=- V & =- [- 4 2 i + 2 y 2 j ] & =-[-2 i +y j ] at x=1, y=1 & =2 i - j V / m aligned
