Question

Help Please! A point charge is place at the origin of a cartesian coordinate system. Another point charge is placed at the coordinates (0, -5.0 m), and a third charge is placed at (7.0 m, 0). If all three particles have a charge of 3.0 μC, find

a)the magnitude of the net force on the charge at (0, -5.0 m)

b)the direction (measured in degrees from the negative x-axis) of the net force on the charge at (0, -5.0 m).

Please show all the steps!

Answer 1

* q = 34100c (0,0) le (7,0) enq (0,-512 FO Ž → AB → Force on charge charge at A due to charge charge q at A AO - force on af 0. Ē AB → Force on at B charge at A due to charge so F - FRO + FAR Faro = - kq ] = {(3.24x103) NJEJ) ©A)? FAB Coso E = - FAR sino i kq2 174 5 . IN N AB² 74

so, Cal0095810 AB + 32 27 4 5. vo IN FAB #² = FAO FATA = (-8.918184 & - 3.88 x103 %) (a I ELS 3.98x103 N b. Direction from Eve x-anie go -0 = 12.930] 907 to - tant (38.8 8.91 12.930
