Questions
Statement A: The time period of a simple pendulum of infinite length is infinite.
Statement B: The time period of a simple pendulum is directly proportional to the square root of length.
detailed solution
Correct option is B
If length of the pendulum is large, g no longer remains vertical but will be directed towards the centre of the earth and expression of the time period is given byT = 2π1g(1l+1R)Here, R is the radius of earth.if l → ∞, 1l→0and T = 2πRg = 84.6 minIn general, time period of a simple pendulum T = 2πlgor T ∝ lTalk to our academic expert!
