Question

What is the time period of a pendulum of length 9.8 m?

Answer 1

==================================
⭐⭐⭐⭐⭐ ANSWER ⭐⭐⭐⭐⭐
==================================

Let, T = Time period, l = length of pendulum and g = acceleration due to gravity.

We know that, l = 9.8 m & g = 9.8 m/s²


Then, by formula,

T = 2 π √(l/g)

=> T=2×22/7×√(9.8/9.8)

=> T = 44/7 × 1

=> T = 44/7 seconds

=> T = 6.28 seconds [REQUIRED ANSWER]
