Imagine that when you place a point test charge with a magnitude of 120 nC at a certain point in space, you find that it experiences a net force of 0.3 mN. What is the magnitude of the electric field at this point?
Ans: 2.5 kN/C
How do I get there?

use the equation
F = q E where F is the force, q the charge and E the electric field
E = F/q = 3x10^-4N/1.2x10^-7C = 2500N/C
F = q E where F is the force, q the charge and E the electric field
E = F/q = 3x10^-4N/1.2x10^-7C = 2500N/C
