Two identical small insulating balls are suspended by separate 0.291m threads that are attached to a common point on the ceiling. Each ball has a mass of 7.90×10-4kg. Initially the balls are uncharged and hang straight down. They are then given identical positive charges and, as a result, spread apart with an angle of 35.0o between the threads. Determine the charge on each ball. This is my third time posting this question :(

Two balls are suspended from the ceiling by parallel strings so that they touch each other.. The masses of the balls are 200 g and 100 g. The heavier ball is raised so that its center of mass is now 4.5 cm higher than earlier. Then the ball is released and allowed to collide with each other. If the collision is elastic, find the final heights of the center of masses of the two balls after the collision?

A pendulum is attached to the ceiling by two 1.7 m long strings. The 30 kg block is composed of wood and can be used to measure the initial speed of a 40 g bullet, by finding the height, h, for the resulting block’s swing after the bullet hits. If the strings attached to the block swing to a maximum angle of 4.7° with respect to the vertical, find A) The potential energy of the system (bullet and block) at...
