Two 45.0 x 10-9 C point charges are located on the x axis. One is at x = 0.25 m, and the other at x = - 0.25 m.
1) A third identical charge is placed on the y axis at y = 0.25 m. discover the magnitude of the force acting on this third charge? Answer in Newton’s.
2) Now the third identical charge is placed on the y axis at y = 2 x 0.25 m. discover the magnitude of the force acting on this third charge? Answer in Newton’s.
