Question

Two pendulums C and D are suspended from a wire as shown in the figure given below. Pendulum C is made to oscillate by displacing it from its mean position. It is seen that D also starts oscillating. Name the type of oscillation, C will execute (ii) Name the type of oscillation, D will execute. (iii) If the length of D is made equal to C then what difference will you notice in the oscillations of D? (iv) What is the name of the phenomenon when the length of D is made equal to C? ​

Answer 1

1. Natural vibration Will be experienced by c

2.d will execute forced vibration

3.both will oscillate together in the opposite sides with same speed to balance their energies between them

4.resonance

Answer 2

(1):- free or natural vibrations are experienced by c

(2):- d will have forced vibration

(3):- if it is done so the amplitude of oscillation will become same

(4):- the phenomenon is named as Resonance.
