The problem is defined below:(adsbygoogle = window.adsbygoogle || []).push({});

The electric field on the surface of an irregularly shaped conductor varies from 56 kn/c to 28 kn/c. calculate the local surface charge density at the point on the surface where the radius of curvature of the surface is (a) greatest and (b) smallest.

Attempt at a solution:

Yet to start, b/c don't understand any further steps with such little information

Extra question:

If they only give us 2 numbers of an irregularly shaped object, how are we supposed to manipulate these numbers to find the local surface charge density?
