alleryHow is a pendulum's period related to its length for small swings?
AInversely linear to L
BProportional to sqrt(L)
CIndependent of length L
DProportional to cube L
Answer & Solution
Correct answer: B. Proportional to sqrt(L)
Galileo determined that the period is proportional to the square root of pendulum length.
