15 positive charges of q are distributed uniformly over the circumference of a circle with radius a. Then another charge of +Q is placed at the center of the circle. Which of the followings are true for this system? 1. +Q The force acting on +Q is zero. II. If +Q is displaced perpendicular to the surface by a small amount and released, it does not come back to the center. III. The electrostatic potential energy of +Q is 159Q IV. The magnitude of the electric field on +Q is 15q0/axeqa² •

Hawkeye draws his compound bow and shoots an arrow. The 23 g arrow leaves the bow with a velocity of 88 m/s. The power stroke of the bow is 57 cm; that is, the bowstring exerts force on the arrow through a displacement of 57 cm. The peak draw weight of the bow is 312 N. (This is the maximum force that the archer has to exert on the bowstring). How much kinetic energy does the arrow have after Hawkeye releases it? How much work does the bowstring do on the arrow? What average force does the bowstring exert on the arrow?
