Physics

A 2 kg pendulum bob is hanging from a 30 cm long piece of string. If the pendulum bob is allowed to move in circular motion in a horizontal plane, determine the tension in the string if the angle the string makes with the vertical is 37 degrees.
Need Step by step solution.

  1. mg is the downward force, mv^2/r is the centripetal force, tension is the string force at the angle.

    Tan theta= tension/mg

    solve for tension.
