Question

Two simple pendulums, A and B, have the same length, but themass of A is twice the mass of B. Their vibrational amplitudes areequal. Their periods are TA and TB,respectively, and their energies are EA andEB. Choose the correct statement and explain. a) TA = TB and EA >EB b) TA > TB and EA> EB c) TA > TB andEA < EB d) TA = TB and EA <EB Two simple pendulums, A and B, have the same length, but themass of A is twice the mass of B. Their vibrational amplitudes areequal. Their periods are TA and TB,respectively, and their energies are EA andEB. Choose the correct statement and explain. a) TA = TB and EA >EB b) TA > TB and EA> EB c) TA > TB andEA < EB d) TA = TB and EA <EB d) TA = TB and EA <EB

Explanation / Answer

And we know the formula for the total energy is E =(1/2)kA2                = (1/2)(m2)A2                 So EA > EB So correct option is (a)
