We are dealing with the small angle pendulum formula, here: T = 2 pi sqrt(L/g)
We can do something very similar to ETS2017 P1, here. We will select which of the two variable ratios to give, and which one the user must find. The ratios must be selected so that L/g is a perfect square. This can be accomplished by selecting the squares of friendly fractions. All AB statements should have randomized order.
There will be a 50% chance that the masses of A and B are not identical, but disparate. This is useless information! But it will serve to nail that point into a user's head.
