The time period of a simple pendulum depends on its length. The longer the length, the longer it takes for the pendulum to complete one oscillation.
Effect of increasing the length of a simple pendulum by 1%
When the length of a simple pendulum is increased by 1%, it means that the new length is 101% of the original length. Let the original length be L, and the new length be L'. Therefore,
L' = 1.01L
Effect on time period
The time period of a simple pendulum is given by the formula:
T = 2π√(L/g)
where T is the time period, L is the length of the pendulum, and g is the acceleration due to gravity.
Substituting L' for L, we get:
T' = 2π√(L'/g)
= 2π√((1.01L)/g)
= 2π(1.005)√(L/g)
Therefore, the new time period is 1.005 times the original time period.
Calculating the percentage increase
To find the percentage increase in the time period, we can use the formula:
% increase = (new value - old value)/old value × 100%
Substituting the values, we get:
% increase = (T' - T)/T × 100%
= (1.005T - T)/T × 100%
= 0.5%
Therefore, the time period of the pendulum increases by 0.5% when the length is increased by 1%. The correct answer is option C.
