Four pendulums A, B, C and D are suspended from the same elastic suppo

1.	Four pendulums A, B, C and D are suspended from the same elastic support as shown in figure. A and C are of the same length, while B is smaller than A and D is larger them A. If A is given a transverse displacement,
Answer» D will vibrate with maximum amplitude C will vibrate with maximum AMLITUDE B vibrate with maximum amplitude All the four will oscillate with equal amplitude Solution :Though the ELASTIC support the DISTURBANCE is transferred toall thependulum. A and C are having same length, hence they will bein resonance and so its amlitude of A and C will be maximum. Here we have assessed that support is completely elastic and hence no damped oscillationoccur. Since length of PENDULUM A and C is same and amplitude of A and C are maximum. Here we have assessed that support is completely elastic and hence no damped oscillation.
