Question

calculate the time period of a simple pendulum whose length is 250cm and g=10m/s​

Answer 1

Given:

Calculate time period of a simple pendulum

To find:

Calculate time period of a simple pendulum whose length is 250 cm.

Solution:

From given, we have,

The length of a simple pendulum is 250 cm and g = 10 m/s2

250 cm = 2.5 m

The time period of a simple pendulum is given by,

T = 2π √[L/g]

where, L = length of a simple pendulum

T = 2 × 3.142 × √[2.5/10]

T = 2 × 3.142 × √0.25

T = 2 × 3.142 × 0.5

T = 3.142 s

Therefore, the time period of a simple pendulum is 3.142 s
