- Not positive, but I think that
V = 4 * 8.99e9N·m²/C² * 1e-19C / ((0.01m)²/2) = 7.20e-5 V
2. Each particle has potential energy
U = 8.99e9N·m²/C² * (1e-19C)² * (2cos45º + 1/2) / (0.01m)²)
U = 1.72e-23 J
which becomes KE:
1.72e-23 J = ½mv² = ½ * 3e-9 kg * v²
v = 1.07*e-7 m/s

Q#1 Create the free-body diagram for particle 3.(just need free body diagram for particle 3) Three particles are fixed on an x axis. Particle 1 of charge q1 is at x = - a, and particle 2 of charge q2 is at x = + a. If their net electrostatic force on particle 3 of charge + Q is to be zero, what must be the ratio q1/q2 when particle 3 is at x = 1.50a? Important: Assume that the...
