Phease show steps!

thanks

Three point charges are placed on the x-axis as follows: 22 mu C at x = 0; 30 mu C at x = 0.40m: and -12 mu C at x = 1.1m. Find the net force on the 22 mu C point charge. Assume the direction of the x-axis as positive. Express your answer to two significant figures and include the appropriate units. Find the net force on the 30 mu C point charge. Express your answer to two significant figures and include the appropriate units. Find the net force on the -12 mu C point charge. Express your answer to two significant figures and include the appropriate units.

Explanation / Answer

A) Net Force = 8.98 * 109 * 10-12 * (- 22 * 30/0.42 + 22 * 12/1.12)

                          = - 35.083 N

B) Net Force = 8.98 * 109 * 10-12 * ( 22 * 30/0.42 + 30 * 12/0.72)

                          = 43.64 N

C)    Net Force = 8.98 * 109 * 10-12 * (- 12 * 30/0.72 - 12 * 22/1.12)

                          = - 8.55 N
