Q33 of 35 Page 143

You have made a pendulum by tying a stone to a string. Its time a period is 1 second, and you want to reduce the time period. How will you achieve this?

The time period of a pendulum can be related as,


where, T s the time period of a pendulum


l is the length of pendulum


g is the gravitational acceleration


as, 2π and g are constant in value so, T is directly proportional to l.


Now, to decrease the period, length must also be decreased.
