The time period ‘T’ of a simple pendulum depends on its length ‘l’ and acceleration due to gravity ‘g’ using unit dimensions. The correct equation for the time period is:

- A
Option A
- B
Option B
- C
Option C
- D
Option D
T=2πgl
The period of a simple pendulum is given by T = 2 gl, where l is the length of the pendulum and g is the acceleration due to gravity.
The time period is directly proportional to length and inversely proportional to gravity.
g should be in the denominator and l in the numerator
It is the formula of frequency
Correct
Should be k, not 1/k
