A 5 C charge moves at 15 km/s in the +x direction, and a –7 C charge moves at 10 km/s in the –y direction. What is the force on the 5 C charge due to the –7 C charge when the 5 C charge is at (0,5 cm) and the -7 C charge is at (-1 cm,0)? Is the force on the 5 C charge larger, smaller or equal to the force on the –7 C charge? Assume gravity has no impact on this problem.
