Two small smooth sphere A and B have equal radius. the mass of A is 4m kg and the mass of B is m kg. The spheres are moving on a smooth horizontal plane and they collide. Immediately before the collision the velocity of A is (2i + 3j) ms-1 and the velocity of B is (3i - j) ms-1. Immediately after the collision the velocity of A is (3i + 2j) ms-1. Find a. the velocity of B immediately...

Two positively charged metal spheres are suspended from the same hook by light strings of equal length, making an angle of 10.0 degree with each other. The charges carried by the spheres are as shown in the diagram. After that, the spheres are brought in contact briefly, then released. If the mass of each sphere is 4.00 g, calculate the length of each string. the new angle theta between the two strings.
