Question:

A +5 micro-Coulomb test charge is placed in an electric field with a strength of -12 N/C at a distance of 10 millimeters. What would be the resulting force experienced by the test charge and would it be attractive or repulsive?

Andrew H.

6x10^-5 Newtons and it would be an attractive force due to the fact the charges are opposite (positive and negative).
