Question

Find the time period of a simple pendulum of length 90 cm at a place where g=10 m/s2.

Answer 1

Explanation:

time =1.88 sec

like my answer

Answer 2

Answer:

Concept:

The time period of a pendulum, or each full oscillation, is constant.

                                      T = 2π √L/g,  

where, L is the pendulum's length and

           g is the acceleration brought on by gravity,

            is the formula for a pendulum's period.

Explanation:

Due to the fact that, for short arcs, the time needed for a full swing (period) depends only on the length of the pendulum and is essentially independent of the extent of the arc, the pendulum is a trustworthy timekeeper.

Given:

Length  = 90 cm

where, g = 10m/s2

Find:

Time period of a simple pendulum

Solution:

By substituting the values in the formula

                       T = 2π √L/g,  

                        T =  2π √90/10m/$s^{2}$

                        T =  18.8 sec

The time period of a simple pendulum of length 90 cm at a place where g=10 m/$s^{2}$ is 18.8 sec
