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

`sqrt3N//C`

`4N//C`

`5N//C`

`20N//C`

Text Solution

Verified by Experts

The correct Answer is:

`W=Fscostheta=qEs costheta`
`:. E=W/(qscostheta)`
`=4/(0.2xx2xxcos60^@)`
`=20 N//C`
