A simple pendulum completes 10 oscillations in 25 seconds. Another simple pendulum completes 11 oscillations in same time. Compare the lengths of two simple pendulums.


brijeshsahani6pdrbly: A simple pendulum makes 10 oscillations in 20 seconds. ... Time period=2 sec. Frequency =1/T=1/2=0.5 Hz ∴Time period and frequency of its oscillation are 2sec and 0.5 hertz. 4.4.

your answer is ---

°•° A simple pendulum completes 10 oscillation in 25 second

So, it's time period is T1 = 10/25 sec

•°•

T1 = 2π√L1/g

=> T1^2 = 4π^2 ×L1/g

=>( 10/25 )^3= 4π^2×L1/g

=> (100/625×g)/4π^2 = L1


°•° another pendulum complete 11 oscillation in 25 second

So, it's time period is T2 = 11/25 second

•°•

T2 = 2π√L2/g

=> (11/25)^2 = 4π^2×L2^2/g

=> (121/625×g)/4π^2 = L2

•°•

L1/L2 = 100/121
