An insulating rod of length 8.0-cm and charge 30 nC is in a plane with a long straight uniform line charge. The linear charge density of the long line charge is 2.4 10-7 C/m. What is the electric force on the rod if the end closest to the line charge is 2.0 cm away? Hint: the electric field from an infinitely long straight uniform line charge is E(r) = 2 k ?/r. Answer is in Newtons.
