Class XI

The displacement of a particle executing S.H.M is given by y=0.25 sin 200 t cm. The maximum speed of the particle is
  1. 50 cm/sec
  2. 0.25 cm/sec
  3. 200 cm/sec
  4. 100 cm/sec
If the maximum velocity and acceleration of a particle executing S.H.M are equal in magnitude, the time period will be
  1. 1.57 s
  2. 6.28 s
  3. 3.14 s
  4. 12.56 s
In simple models damping force is
  1. inversely proportional to acceleration
  2. inversely proportional to velocity
  3. directly proportional to acceleration
  4. directly proportional to velocity
Which one of the following equations does not represent S.H.M?
  1. Y= A cos ωω t + B
  2. Y= A sin ωω t + B cos ωω t
  3. Y= A sec ωω t + B cosec ωω t
  4. Y=A sin ωω t
What is constant in simple harmonic motion?
  1. Potential energy
  2. Periodic time
  3. Restoring force
  4. Kinetic motion
