What is the formula for the period of a simple pendulum?.
- A.T = 2π√(L/g)
- B.T = 2πL/g
- C.T = g/2π√L
- D.T = L/(2πg)
Model answer
What a good answer should say
- T = 2π√(L/g)
Explanation
Why this works
The formula for the period (T) of a simple pendulum is derived from the relationship between the length of the pendulum (L) and the acceleration due to gravity (g). It shows that the period is proportional to the square root of the length divided by the gravitational acceleration.
