Question

Need help with physics problem.

You have a summer job with the telephone company investigating the vulnerability of underground telephone lines to natural disasters. Your task is to write a computer program that will be used determine the possible harm to a telephone wire from the high electric fields caused by lightning. The underground telephone wire is supported in the center of a long, straight steel pipe that protects it. When lightening hits the ground it charges the steel pipe. Since you think that the largest field on the wire will be where it leaves the end of the pipe, you calculate the electric field at that point as a function of the length of the pipe, the radius of the pipe, and the charge on the pipe.

Answer 1

I don't see any role of a computer program here. But I'll find the electric field of the cylinder.
