Two point charges, with charges q1 and q2, are each moving with speed v toward the origin. at the instant shown q1 is at position (0,
d.and q2 is at ( d, 0). (note that the signs of the charges are not given because they are not needed to determine the magnitude of the forces between the charges.) part a what is the magnitude of the electric force between the two charges? express f in terms of q1, q2, d, and ϵ0.
