Three is an electric field E in the x - direction. If the work done by the electric field in moving a charge of `0.2 C` through a distance of `2 m` along a line making an angle `60^(@)` with the x- axis is `4 J`, then what is the value of E ?

`sqrt(3) N//C`

`4 N//C`

`5 N//C`

None of these

Text Solution

Verified by Experts

The correct Answer is:

`W = qE cos 60^(@) xx 2`
`4 = 0.2 E rArr E = 20 N//C`
