Homework Statement
An infinite plane of charge has surface charge density 6.8 µC/m2. How far apart are the equipotential surfaces whose potentials differ by 100 V? In mm
Homework Equations
E=σ/(2ε0)
The Attempt at a Solution
So first I solved for E= 6.8e-6/(2*8.85e-12) = 384170.791
then because ΔV= E *ΔX
so
ΔX=ΔV/E
so then I substituted
ΔX = 100/ 384170.791
ΔX = .0002603
The site says that I've made a power of ten error the answer must be in mm but I'm not sure what I am doing wrong
