Question

the length of simple pendulun is incresed by 21%.THEN the % increased in the TIME PERIOD of simple pendulum is

Answer 1

Answer:

Explanation:

Time period = 2π*√length/gravitational acceleration

So, New length = length + 21/100(length) = 121/100(length)

So, New time period = 2π*√new length / gravitational acceleration

= 2π*11/10*√length/gravitational acceleration

= 1.1 * Original time period

So, that means the time period increases by 10%
