Electric potential due to a space is given by (x, y, z)= ₀ x₀ x ; when x₀=5 ~m and ₀=8 V . Find the electric field at (10 ~m , 5 ~m , 5 ~m )
Options
- A0.40 Vm ⁻¹ i
- B-0.40 Vm ⁻¹ i
- C4.0 Vm ⁻¹ i
- D-4.0 Vm ⁻¹ i
Correct answer
A. 0.40 Vm ⁻¹ i
Step-by-step solution
We have E=- d v d x =- d d x [ ₀ x₀ ] x =- ₀ x₀ - 1 x^2 = 40 x^2 So, . E |_ (10,5,5) = 40 10^2 =0.4 ~V / m
