A. An engineer builds two simple pendula. Both are suspended from small wires secured to the ceiling of a room. Each pendulum hovers 2 cm above the floor. Pendulum 1has a bob with a mass of 10 kg. Pendulum 2 has a bob with a mass of 100 kg. Describe how the motion of the pendula will differ if the bobs are both displaced by 12o.
The motion of the pendula will not differ because the mass of the bobs has no role in the motion of simple pendulum.
The pendula is only affected by the change in time period. The time period of a pendulum is given by
, where L = length of pendulum and g = acceleration due to gravity.
