A magnetic force of 3.2x10-12 N in the -z direction is acting on an electron
(q=-1.6x10-1°C) moving 1.0x10?m/s in the +y direction. What is the magnitude and
direction of the magnetic field?

Atriangle with equal sides of length 10 cm has -2.5-nc charged objects at each corner. part a determine the direction of the electrical force exerted on the object at the top corner due to the two objects at the horizontal base of the triangle. determine the direction of the electrical force exerted on the object at the top corner due to the two objects at the horizontal base of the triangle. horizontally rightward vertically downward vertically upward horizontally leftward
