In the following diagram the work done in moving a point charge from point `P` to point `A, B` and `C` is respectively as `W_(A), W_(B) and W_(C)`, then

Options

A. `W_(A) lt W_(B) lt W_(C)`
B. `W_(A) gt W_(B) gt W_(C)`
C. `W_(A) = W_(B) = W_(C)`
D. None of these

Answer

3

Explanation

`V_(A) = V_(B) = V_(C )`
`W_(A) = q(V_(A) - V_(P)) , W_(B) = q(V_(B) - V_(P)) , W_(C ) = q(V_(C ) - V_(P))`
`W_(A) = W_(B) = W_(C )`
