A +10nC charge is located at (x, y) = (0 cm, 10 cm) and a -5.0 nC charge is located (x, y) = (5.0 cm, 0 cm). Where would a -10 nC charge need to be located in order that the electric field at the origin be zero?

Need in all of themmm only answer if you know plsssss

The force it would take to accelerate an 900-kg car at the rate of 6m/s2

The magnitude of the magnetic field at a certain distance from a long, straight conductor is represented by b. what is the magnitude of the magnetic field at twice the distance from the conductor? a. at twice the distance, the magnitude of the field is 4b.b. at twice the distance, the magnitude of the field is 2b.c. at twice the distance, the magnitude of the field is b/2.d. at twice the distance, the magnitude of the field is b/4.e. at twice the distance, the magnitude of the field remains equal to b.
