L o r e n t z f o r c e = q E q = c h a r g e o f c h a r g e p a r t i c l e

E = e l e t r i c f i e l d s t r e n g t h f o r c h a r g e p l a t e

w o r k d o n e = q E d

d = d i s p l a c e m e n t

q = 2 C d = 1 m m

E = \frac{σ}{2 ϵ_{0}} (f o r n o n c o n d u c t i n g s h e e t)

E = \frac{σ}{ϵ_{0}} (f o r c o n d u c t i n g s h e e t)
