Question

The effective length of a pendulum is related with time period as : (1) T2 ∝ l2 (2) T3 ∝ l (3) T2 ∝ l (4) T ∝ L3

Answer

T² ∝ l

Reason — The time period of oscillation is directly proportional to the square root of its effective length i.e., T ∝ √l or in other words, the square of time period of oscillation (T²) is directly proportional to its effective length (l) i.e., T² ∝ l.
