Two charges, +7 µC and +17 µC, are fixed 1 m apart, with the second one to the right. Find the magnitude and direction of the net force (in N) on a −3 nC charge when placed at the following locations.   (a) halfway between the two magnitude  N direction        (b) half a meter to the left of the +7 µC charge magnitude  N direction        (c) half a meter above the +17 µC charge in a direction perpendicular to the line joining the two fixed charges (Assume this line is the x-axis with the +x-direction toward the right. Indicate the direction of the force in degrees counterclockwise from the +x-axis.) magnitude  N direction  ° counterclockwise from the +x-axis
