Acharge of +2.00 x 10^-9 c is placed at the origin, and another charge of +4.50 x 10^-9 c is placed at x = 1.6 m. the coulomb constant is 8.98755 x 10^9 n m2/c2. find the point (coordinate) between these two charges where a charge of +3.70 x 10^-9 c should be placed so that the net electric force on it is zero.

Tafari worked one summer on a ship that set weather buoys in the ocean. he watched how one of the buoys moved in the water. describe which parts of the wave would cause the buoy to bob up and down. which wave property determined how fast the buoys bobbed in the water? he observed that when the wind blew harder, the ocean waves were larger, and the buoys moved away from the ship. what effect, if any, did the waves have on how far the buoys moved? explain your answer.
