Question: A circular arc has a uniform linear charge density of 8 nC/m. The value of the Coulomb constant is 8.98755 x 109 N.m2/ C2.
What is the magnitude of the electric field at the center of the circle along which the arc lies? The radius of the arc is 2.4 m and it goes 262 degrees around the center, starting at the positive x axis.
Answer in units of N/C
