Problem

Three small-angle pendulums are set into motion. • Pendulum A: length

0.50\,\text{m}

on Earth (

g = 9.8\,\text{m/s}^2

) • Pendulum B: length

2.0\,\text{m}

on Earth (

g = 9.8\,\text{m/s}^2

) • Pendulum C: length

0.50\,\text{m}

on Mars (

g = 3.7\,\text{m/s}^2

) Which ranking correctly orders the frequency

f

of oscillation from greatest to least? (a)

f_B > f_C > f_A

(b)

f_B > f_A > f_C

(c)

f_A > f_C > f_B

(d)

f_C > f_A > f_B
