A coaxial cable consists of alternating coaxial cylinders of conducting and insulating material. a. True
b. False

True

Explanation:

A coaxial cable is a type of cable that has an inner conductor surrounded by an insulating layer, surrounded by a conductive shielding.

f=ma newton

f=100x2.5=250n

force required to detach it is given by

charges are taken to be fundamental charge

now we have

so above is the minimum distance at which it will detach
