An infinite plane sheet of charge density `10^(-8) Cm^(-2)` is held in air. In this situation how far apart are two equipotenitial surfaces, whose p.d is 5 V ?

Text Solution

Verified by Experts

Here , `sigma = 10^(-8) C//m^(2) , dv = 5V`
Since `E = (dV)/(dr)` ( neglecting - ve sign with dV/dr and `E = (sigma)/(2 in_(0))` (for an infinte plance charged sheet )
`(sigma)/( 2 in_(0)) = (dV)/(dr)` or `dr = (2 in_(0) dv)/(sigma) = (2(8.85 xx 10^(-12) C^(2)//Nm^(2)) (5V))/(18^(-8)C//m^(2))`
` = 8.85 xx 10^(-3)m = 8.85 mm`
