Question

While noting the time period of a simple pendulum amplitude of vibration should be kept-

• A. Reasonably large for easy measurement
• B. As small as possible
• C. Without any restriction
• D. Very large because formula T = 2p$\sqrt{\frac{\mathcal{l}}{g}}$ is derived accordingly

Answer 1

Answer: (B)

As small as possible

Answer 2

T = 2p $\sqrt{\frac{\mathcal{l}}{g}}$ is derived by assuming sin q to be negligibly small so q should be very small.
