STANDARD Physics Simple Pendulum MCQ Question
As the temperature is increased, the time period of a pendulum
increases as its effective length increases even though its centre of mass still remains at the centre of the bob.
decreases as its effective length increases even though its centre of mass still remains at the centre of the bob.
increases as its effective length increases due to shifting of centre of mass below the centre of the bob.
decreases as its effective length remains same but the centre of mass shifts above the centre of the bob.
Correct Answer
Detailed Explanation
Time period of the simple pendulum is T = 2π√(L/g). With increase in temperature, the effective length (L) of simple pendulum increases even though its centre of mass still remains at the centre of the bob. From (i), T ∝ √L. So T increases as temperature increases.
