Question:
(a) What is the electric field strength due to a point charge of 2.4 at a position 8.6 cm away from the charge?
(b) What is the magnitude of the electric force on a charge of −3.4 that is 8.6 cm away from the point charge in part a?
(c) Draw a sketch of the two charges, from parts a and b, and indicate the direction of the electric force on the second charge due to the original point charge.
