Numerical problem worksheet based on the time period of pendulum

Full solution of Numerical worksheet based on the pendulum’s time period equation

Q1 ) solution:

T = 2π (l / g )^1/2

l = 6 m

T = 2π (6 / 10 )^1/2 = 4.86 sec

Q2 ) solution:

T =time for 1 oscillation= 60/24 s= 2.5 sec

T = 2π (l / g )^1/2

=> l = g. T²/(4 π²) = 10. (2.5)² /(4.π²) = 1.58 m

Q3 ) solution:

T = 2π (l / g )^1/2 = 2π (3.6 / 10 )^1/2 = 3.79 s
