An infinite plane of charge with `sigma=2 in_(0) C/m^(2)` is tilted at a `37^(@)` angle to the vertical direction as shown below. Find the potential difference, `V_(A)-V_(B)` in volts, between points A and B at `5 m` distance apart. (where B is vertically above A).

Answer

3

Explanation

`E=sigma/(2 epsilon_(0))=1 N//C :. V_(B)-V_(A)=-int vec(E).dvec(l)=(sigma/(2 in_(0)))(5 cos 53^(@))=3V`
