The pendulum of a clock is replaced by a spring mass system with the spring having spring constant 0.1 N/m.What mass should be attached to the spring?

Juhi Sharma

we know that time period of the pendulum = 1s.

also time period of spring mass system =

therefore by equating time period by 1 we get

m = 4π²k

here k = 0.1

therefore m =3.947 kg.
