Electric Field Due to Disk and Infinitely Large Sheet

←5 V / m |σ20...

Question

Electric field close to plane of charge is shown in figure. External electric field in V/m is

Open in App

Solution

let external field be $E_{o}$
$E_{1} = E_{o} + \frac{σ}{2 ϵ_{o}} = 20$ --(1)
$E_{2} = \frac{σ}{2 ϵ_{o}} - E_{o} = 5$ --(2)
By (1) - (2) $E_{o}$ = 7.5
