TRUE and FALSE
Again, it is useful to draw on the mechanical analogy to explain this. The two mechanical oscillators have the same natural frequency of oscillation, so m1 /k1 and m2 /k2 are the same. (Remember: m plays the role of L, and 1/k plays the role of C). Since the total energy U is the same for both oscillators, the maximum K.E. and the maximum P.E. are both equal to U. Thus

( m1 v12 / 2)max = U = ( m2 v22 / 2)max

and since we are given that m1 and m2 are different, the maximum velocities must be different.
