Three charges are fixed to an x, y coordinate system. A charge of +20 µC is on the y axis at y = +3.0 m. A charge of -10 µC is at the origin. Lastly, a charge of +43 µC is on the x axis at x = +3.0 m. Determine the magnitude and direction of the net electrostatic force on the charge at x= +3.0 m. Specify the direction relative to the -x axis.
A charge of −1 Coulomb is placed at the 100-cm mark of the same meter stick. Elucidate is it possible to place a proton somewhere on the meter stick so that the net force on it due to the two charges is 0?
