9. Two charges of 10 C and –4 C are 2 m apart. (a) What is the electric potential at a point midway these charges? (b) What is the potential at a point between the charges and 0.667 m away from the –4 C charge? (c) How much work would be required to move a 0.05 C charge from the midpoint to the 0.50 m mark?   pls write legibly thanks

look at the pic..

5. A particle of unknown charge obtains 0.042 J of kinetic energy as it moves from point A to point B. Point Ahas an electric potential of 700.0 V; and point B has an electric potential of 200.0 V. Determine the magnitudeand sign of the charge.

How much work is done (by a battery, generator, or some other source of potential difference) in moving Avogadro's number of electrons from an initial point where the electric potential is 9.10 V to a point where the electric potential is -7.60 V? (The potential in each case is measured relative to a common reference point.) MJ Need Help? Watch It

A uniform electric field of magnitude 255 V/m is directed in the negative y direction as shown in the figure below. The coordinates of point O are (-0.900, -0.400) m, and those of point ® are (0.600, 0.850) m. Calculate the electric potential difference V. - V, using the dashed-line path. 510 Va - V, is the work required to move a test charge from point A to point B. V
