Step 1
Given in question - Electric field (E) = N/c
To find - Surface charge density() on the drum.
Solution - Step1 - Here we will understand the concept that will be used to solve this question.
As we know, Electric field on the surface of the conductor is given by -
So the surface charge density() = ..........(1)
The value of
