An iron bolt of mass 55.0 g hangs from a string 34.1 cm 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 28.5 cm to the right from the previously vertical line of the string.
(a) Draw a free-body diagram of the bolt.
(b) Find the tension in the string.
(c) Find the magnetic force on the bolt.
