NEET Physics: Oscillations — MCQ Test 5

Q6. In a simple pendulum executing SHM, what ensures that the period is independent of the initial angular displacement?

Q7. A particle in SHM has \( x = 3 \cos (2t + \frac{\pi}{6}) \) (in m). What is its speed at \( t = 0.5 \, \text{s} \)? (Take \( \sin \frac{4\pi}{6} = 1 \))

Q8. A spring-mass system has \( T = 0.2 \, \text{s}, m = 0.8 \, \text{kg} \). What is the spring constant?

Q9. A particle in SHM has an amplitude of \( 12 \, \text{cm} \) and a period of \( 1.2 \, \text{s} \). What is its maximum velocity? (Take \( \pi = 3.14 \))

Q10. In SHM, why does the particle’s velocity lead its displacement by \( \pi/2 \) radians?

Q11. A mass of \( 2 \, \text{kg} \) is attached to a spring with \( k = 200 \, \text{N/m} \). What is the frequency of oscillation?

Q12. A particle in SHM has \( x = 6 \sin (2\pi t + \frac{\pi}{4}) \) (in cm). What is its acceleration at \( t = 0.25 \, \text{s} \)?

Q13. A particle’s displacement is \( x = 7 \sin (2t + \frac{\pi}{4}) \) (in m). What is its velocity at \( t = 0 \, \text{s} \)? (Take \( \cos 45^\circ = \frac{\sqrt{2}}{2} \))

Q14. A particle in SHM has \( x = 3 \sin (4t + \frac{\pi}{3}) \) (in m). What is its acceleration at \( t = 0.25 \, \text{s} \)? (Take \( \cos 60^\circ = 0.5 \))

Q15. Why does the frequency of a spring-mass system increase when a stiffer spring is used?
