A conductor of any shape, having area 40 cm2 placed in air is uniformly charged with a charge 0* 2µC. Determine the electric intensity at a point just outside its surface. Also, find the mechanical force per unit area of the charged conductor.
[∈0=8.85x10-12 S.I. units]
Given: Q=0.2 μC=0.2*10-6C
The electric field intensity just outside the surface of a charged conductor of any shape is
Now, the mechanical force per unit area of a conductor is
