Can some one please help me with this question?
An iron bolt of mass 121.1 g hangs from a string 1.2 m long. The top end of the string is fixed. Without touching it, a magnet attracts the bolt so that it remains stationary, but is displaced horizontally 0.28 m to the right from the previously vertical line of the string. Find the magnitude of the magnetic force on the bolt.
