A simple pendulum of length/and having a bob of mass M is suspended in a car. The car is moving on a circular track of radius R with a uniform speed \[\theta \approx \theta \]. IS the pendulum makes small oscillations in a radial direction about its equilibrium position, what will be its time period?

Answer:

Centripetal acceleration, \[\text{T=2 }\!\!\pi\!\!\text{ }\sqrt{\text{l/g}}\text{.}\]. It is acting horizontally. Acceleration due to gravity = g acting vertically downwards. Effective acceleration due to gravity \[\theta \] \[\theta \] Time period, \[\theta \]
