The diagram above shows a coaxial cable. The inner conductor has radius a = 0.0025 m. The outer conductor is a cylindrical shell with inner radius b = 0.0075 m, and outer radius c = 0.008 m from the center. Both conductors are coaxial. For every length L = 10 m of cable, there is a total charge q = 2.8e-08 C on the inner conductor and a total charge of Q = -5.6e-06 C on the outer conductor.

Determine the electric potential difference between the labeled points A and B
delta V(A,B) = VB - VA = ______ V

I really need help with this. Someone please help me with this question.
Thanks.
