Question

What effect will doubling the mass of the bob have on the time period of a simple pendulum? (A) Halved. (B) Doubled. (C) Becomes 8 times. (D) No effect.

Tardigrade Admin · Accepted Answer

Time period of a simple pendulum, T=2π √(L/g) It means T is independent of mass of the bob m . Hence, if mass is doubled, T will not change.

Q. What effect will doubling the mass of the bob have on the time period of a simple pendulum?

Halved.

Doubled.

Becomes $8$ times.

No effect.

Time period of a simple pendulum, $T = 2 π \frac{L}{g}$
It means $T$ is independent of mass of the bob $m$ . Hence, if mass is doubled, $T$ will not change.
