How do you do the problems on the right? all of the problems relate back to the one on the top left. Please explain it to me.

Simultaneous Round Table f two 2.5 HC charges are 0.3 m apart, what is the If a test charge of 2x10"12 C is placed in line with these force between them? 1 HC = 1x10- C charges, and 0.1 m beyond one of them (not between (2.5 x10 ) ( 9 x 109 N. M 2 ) ( 2. 5 x 10 # ( ) them), what is the net force experienced by this test charge? Note: you will need to do two Fe equations CO. 3 m ) 2 19192 056 25 09 m 0625 N What would happen to the force if the charges were What would happen to the force if one of the charges to have separated by a distance that is 5 times larger was tripled and the other one was cut in half? What is than the original distance? What is the new force? the new force? F. 1 . 1 . 1 52 = 25 Fx = 0.625 x 25 Fa = 0.025N
