Question

Which of the below pendulums will move the slowest, if each one of them is displaced by an angle of $60 \degree$ from the center?

• A.
• B.
• C.
• D.

Answer 1

Answer: (B)

Answer 2

The time period of a pendulum (T) = 2π√(L/g). The time period is directly proportional to the length (L) of the pendulum. A longer time period means a slower pendulum speed. So, Option B is correct.
