Three point charges are placed on the x-axis as follows: 22 mC at x = 0; 30 mC at x = 0.50 m; and -14 mC at x = 1.3 m.
a) Find the net force on the 22 mC point charge. Assume the direction of the x-axis as positive. Express your answer to two significant figures and include the appropriate units.
b) Find the net force on the 30 mC point charge. Express your answer to two significant figures and include the appropriate units.
c) Find the net force on the -14 mC point charge. Express your answer to two significant figures and include the appropriate units.
