A charge of -4.50 10-6 C is placed at a point in space where the electric field is directed toward the right and has a magnitude of 9.00 104 N/C. What are the magnitude and direction of the electrostatic force on this charge?

Question

A charge of -4.50  10-6 C is placed at a point in space where the electric field is directed toward the right and has a magnitude of 9.00  104 N/C. What are the magnitude and direction of the electrostatic force on this charge?

bobpursley · Answer

force=Eq look at direction first, E is to the right (E is the direction a + test charge will do, you are adding a neg charge), so the force will be to the left
