Forces in a Three-Charge System Coulombs law for the magnitude of the force F between two particles with charges Q and Q' separated by a distance d |F| = where K = 1/4pi epsilon 0 and epsilon0 = 8.854 x 10^-12 C2/(N m^2) is the permittivity of free space. Consider two point charges located on the x axis: one charge, q1 = .11.5nC is located at x1 = -1.650m; the second charge, q2 = 36.5 nC, is at the origin (x = 0.0000). Part A What is the net force exerted by these two charges on a third charge q3 = 50.5nC Your answer may be positive or negative. depending on the direction of the force. Express your answer numerically in Newtons to three significant figures. Force on q3 =Explanation / Answer
Here ,
the force on F3 = F2 + F1
F3 = k*q3*(q1/d1^2 + q2/d2^2)
F3 = - 9*10^9 * 50.5 *10^-9 *10^-9 *(11.5/(1.650 - 1.050)^2 + 36.5/1.050^2)
F3 = - 2.96 *10^-5 N
the force acting on the charge q3 is - 2.96 *10^-5 N
