A simple pendulum of length 1.5m has a bob of mass 2.0kg. State the formula for the period of small oscillations and evaluate it
Shalnov [3]

A simple pendulum of length 1.5m has a bob of mass of 2.0kg, then the period for the small oscillations would be 2.456 s.

<h3>What is the frequency?</h3>

It can be defined as the number of cycles completed per second. It is represented in hertz and inversely proportional to the wavelength.

The frequency of a pendulum is the reciprocal of the time period can be given by the following relation,

f = 1/T

As given in the problem A simple pendulum of length 1.5m has a bob of mass of 2.0kg.

The formula for the time period for the pendulum,

T = 2π√L/g

  =2π√1.5/9.81

  =2.456 s

Thus, the period for the small oscillations would be 2.456 s.
