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) = W_(B) = W_(C)`
B. `W_(A) = W_(B) = W_(C) = 0`
C. `W_(A) gt W_(B) gt W_(C)`
D. `W_(A) lt W_(B) lt W_(C)`

Answer

B

Explanation

Charge when moved in a space of no field, does not experience any force and no work is done.
`W_(A) = W_(B) = W_(C) = 0`
