What is the force of q3 on q1 in the y direction, Fy? Give your answer in newtons.

Two charges q1 = 4 µC, 92 = -24 µC, are L = 12 cm apart. A third charge is to be placed on the line between the two charges. How far from q1 should the third charge be placed so that the net electric force on the third charge is minimized? 4.8 cm You need to come up with an equation that represents the net force on the third charge as a function of the distance x, then use appropriate calculus to find the value of x where this net force is a minimum.

Two point charges are located 2.5 mm apart. The force between the particles has a negative magnitude of 4.0N. If the two point charges are moved 5.0 mm apart and everything remains the same, the new face between the charges will have a magnitude of?  I know the answer is 1.0 N but how?

Three equal charges, each of +4.6 pC, are spaced along a straight line. Charge A, is at one end of the line of 1.8 m from the central charge, B. Charge C is the other side of charge B a distance of 2.2 m from charge B. What is the magnitude and direction of the total force on each charge?

Honeybees acquire a charge while flying due to friction with the air. A 130 mg bee with a charge of + 23 pC experiences an electric force in the earth's electric field, which is typically 100 N/C, directed downward.
