Explanation Formula Used: Time period of the pendulum, T = 2 π L g Potential energy, P = m g h Kinetic energy, k = 1 2 m v 2 Given: Time taken by lamp for one oscillation = 5.5 s Maximum angle from the vertical = 3 ° Calculation: (a) We know that, the time period of the pendulum is given by formula, T = 2 π L g Where, g = acceleration due to gravity ( 9.8 m/s 2 ) So, length of the pendulum can be found as L = T 2 ( 2 π ) 2 × g L = T 2 ( 2 π ) 2 × g L = 5.5 2 4 × 3.17 2 × 9.8 L = 296.45 40.19 = 7.37 m (b) When the lamp makes an angle of 3 ° from vertical, the maximum speed of the swinging lamp can be find applying the conservation of energy

Simple harmonic motion

Simple harmonic motion is a type of periodic motion in which an object undergoes oscillatory motion. The restoring force exerted by the object exhibiting SHM is proportional to the displacement from the equilibrium position. The force is directed towards…

Simple Pendulum

A simple pendulum comprises a heavy mass (called bob) attached to one end of the weightless and flexible string.

Oscillation

In Physics, oscillation means a repetitive motion that happens in a variation with respect to time. There is usually a central value, where the object would be at rest. Additionally, there are two or more positions between which the repetitive motion tak…
