A bob B of mass 1 kg is suspended from the ceiling of a toy train as shown in the figure. The train oscillates simple harmonically in horizontal direction with angular frequency ω = 5 rad/s and amplitude a = 0.1m. What is the ratio of maximum and minimumtensions in the string AB during the motion (g = 10 ms−2 & tan 37° = 3/4)
