Two simple pendulums A and B are suspended side by side in the school laboratory where the acceleration due to gravity is 9.8m s−2.
(a) Pendulum A has length 1.00m and time period TA. The time period of pendulum B is observed to be twice that of A. Calculate the length of pendulum B.
(b) The same pendulum B is taken to planet X where the acceleration due to gravity is 3.70m s−2 and its length is unchanged. Determine its time period on planet X.
(c) Comment, with reason, on whether pendulum B will run faster or slower on planet X compared with Earth.
