Two spherical beads (charged equally, with each one weighing 3.10 g) are put 6.70 cm away from each other. If they are let go and begin to accelerate at 118 m/s2, what would be the magnitude of the charge on each bead?
Are they each accelerating at 118 m/s^2 in the direction away from the other or are they each accelerating at 118/2 = 59 m/s^2 so that the rate of change of distance between them is changing at 118 m/s^2
Once you have that F = m a
assuming a = 118
k Q1Q2/x^2 = .00310 (118)
k = 9*10^9
9*10^9 Q^2 = .00310 * 118 * (0.067)^2
