"Six pendulums of mass m and length k as shown are released from rest at the same angle from vertical. Rank the pendulums according to the number of complete cycles of motion each pendulum goes through per min
Rank from most to least complete cycles of motion per minute. To rank items as equivalent, overlap them.

a) L=2m, m=4kg
b) L=2m m=2kg
c) L=4m m=1kg
d) L=1m m=4kg
e) L=1m m =2kg
f) L=4m m=4kg
