Question

what is the next force exerted by these two charges on a third charge Forces in a Three-Charge System Part A What is the net force exerted by these two charges on a third charge q3 -500 nC placed between gy and g2 at Coulomb's law for the magnitude of the force F between two particles with charges Q and Q separated by a distance d is z1.145 m? Your answer may be positrive or negative, depending on the direc tion of the force Express your answer numerically in newtons to three significant figures. where K = TRoard eo = 8.834 x 10 i2 C2/N·m?) is the permittrvity of free space Force on 9s Consider two point charges loc ated on the x axis one charge, q1 =-155 nC is located at --1 695 m the second charge.

Explanation / Answer

Force exerted by charges = KQ1Q2/(r^2)

r = distance between charges

Q1 = -15.5nC

Q2 = 35nC

Q3 = 50nC

r1 = distance between charges Q1 and Q3 = (-1.145+1.695)m = 0.55 m

r2 = distance between charges Q2 and Q3 = (0+1.145)m = 1.145 m

F(1-3),force between Q1 and Q3 = 9*10^(-9)*(-15.5*50)/(.55)^2 = -2.3*10^(-5) N, towards negative X

F(2-3),force between Q2 and Q3 = 9*10^(-9)*(35.5*50)/(1.145)^2 = -1.2*10^(-5) N, towards negative X

Net force on Q3 = -2.3*10^(-5) N - 1.2*10^(-5) N = -3.5*10^(-5) N, towards negative X
