Q1PhysicsUnit 10: Oscillations and Waves
Assertion For a particle performing SHM, its speed decreases as it goes away from the mean position. Reason In SHM, the acceleration is always opposite to the velocity of the particle.
Q2PhysicsUnit 10: Oscillations and Waves
A particle moves along the X-axis according to the equation x=\boldsymbol{x}= 10sin3(πt).10 \sin ^{3}(\pi t) . the amplitudes and frequencies of component SHMs are
Q3PhysicsUnit 10: Oscillations and Waves
Assertion Path of a particle in SHM is always a straight line. Reason All straight line motions are not simple harmonic.
Q4PhysicsUnit 10: Oscillations and Waves
The displacement-time graph of a particle executing SHM is shown in the figure. Then This question has multiple correct options
Q5PhysicsUnit 10: Oscillations and Waves
A body of mass 1/4kg1 / 4 \mathrm{kg} is in S.H.M and its displacement is given by the relation y=0.05sin(20t+π2)m.\boldsymbol{y}=\mathbf{0 . 0 5 \operatorname { s i n }}\left(\mathbf{2 0 t}+\frac{\boldsymbol{\pi}}{\mathbf{2}}\right) \mathrm{m} . If t\boldsymbol{t} is in seconds, the maximum force acting on the particle is:
Q6PhysicsUnit 10: Oscillations and Waves
Three simple harmonic motions in the same direction having the same amplitude a and same period are superposed. If each differs in phase from the next by 45,45^{\circ}, then : This question has multiple correct options
