Question

The time period of a simple pendulum is $2s$. Find its frequency?

• A. $0.5Hz$
• B. $1Hz$
• C. $1.5Hz$
• D. $2Hz$

Answer 1

Answer: (A)

$0.5Hz$

The Time period of a simple pendulum is given as 2 seconds.
The frequency is given as the inverse of time period, that is, $f=\frac{1}{T}$
$f=\frac{1}{2}=0.5Hz$
