Question

magnitudes and algebraic signs of the charges gA and qB. +4.00 C *21. mmh The drawing shows three point charges fixed in place. The charge at the coordinate origin has a value of ql = +8.00 UC; the other two charges have identical magnitudes, but opposite signs: q2 = -5.00 C and q3 = +5.00 uC. (a) Determine the net force (magnitude and direction) exerted on gl by the other two charges. (b) If I had a mass of 1.50 g and it were free to move, what would be its acceleration? 1.30 m 23.0 1.30 m

Answer 1

2 sing 13 No Froso Fcoso 1.3m +5uc 0-54c Since both charge has some magnitude of charge but of opposite sign, so ge will apply alteractive force 1. While q3 prepulsine force 1 so a component of forces got cancelled out y component will contribute to net force Fvet = 2F sino = 2 (8x106) (54156 Gin 23° (1.3)2 Only = 2x9x109x. 40%!0-12 (0.39) (b) 1.6.9 Fret = 0.166 N in y direction m = 1.5 g = 1.5610-3 kg F=ma as E = 0.166x103 1.5 la = 110.67 m/s2
