In an electric field due to charge Q , a charge q moves from point A to B as shown in the figure. The work done is ( ₀= permittivity of free space)
Options
- A1 4 ₀ Qq r ^2
- B1 4 ₀ Qq r ^2 6
- C1 4 ₀ Qq r
- Dzero
Correct answer
D. zero
Step-by-step solution
Electric field is perpendicular to the displacement. F = q E F is also perpendicular to the curved surface aligned W & = dW & = F ds = F ds 90^ W & =0 aligned
