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.

How do the measurements of charge at the different locations on the sphere compare to each other? the charge measurements are different at all locations on the sphere. the charge measurements are virtually not the same at all locations on the sphere except for the charge at the very top and at the very bottom that are equal. the charge measurements are virtually the same at all locations on the sphere except for the charge at the very top. at the top, the conductive sphere has a small disk that is made of different material. the charge measurements are the same at all locations on the sphere. what happens to the charge on the conductive sphere when it is connected to a source of charge such as the electrostatic voltage source? nothing will happen because no charge goes around the surface of the sphere. the charge on the conductive sphere spreads out over the surface of the sphere; being greater in some specific locations on the sphere. the charge on the conductive sphere spreads out uniformly over the surface of the sphere. the charge on the conductive sphere spreads out non-uniformly over the surface of the sphere.
