An iron bolt of mass 75.0 gram hangs from a string 30.1 centimeter long. The top of the string is fixed. Without touching it, a magnet attracts the bolt therefore that it remains stationary, displaced horizontally 22 centimeter to the right from the previously vertical line of the string. Determine the tension in the string. Determine the magnetic force on the bolt.
