Answer how can you increase the period of a pendulum? a. by adding mass b. by making the string longer c. by taking mass away d. by making the string shorter

Time period of simple pendulum is given by formula

here

L = length of pendulum

g = acceleration due to gravity

now as per formula we can see that time period is directly proportional to the square root of the length.

So in order to increase the time period we can increase its length

so correct answer would be

b. by making the string longer

B
