Find the magnitude of the net force on charge qi; draw an arrow showing the direction of this force 1. r12-0.5m 2. r12=0.4m 3. r12-0.3m r23-0.2m 4. 3-10 r12-0.3m r23-0.2m

Answer 1

F = q_1 q_2/r_1 2^2 = (9 times 10^9) (2) (1)/0.5^L = 7.2 times 10^10 N F = (9 times 10^9 (2) (3)/0.4^2 = 3.37 times 19^11 N F_net = F_12 - F_13 = (9 times 10^9) (2) (3)/0.3^2 = (9 times 10^0) (2) (1)/0.5^2 5.28 times 10^11 N F_net = F-12 - F_13 = (9 times 10^9) (3) (2)/0.3^2 - (9 times 10^9) (3) (1)/1.3^2 = 4.92 times 10^11 N
