1. Acceleration of a particle is given by: a = -bx, where "x" is the displacement from the mean position and "b" is a constant. The period of oscillation is: 2n a) b) c) d) b 2. In SHM path length is 4 cm and maximum acceleration is 2n2 cm/s?. Time period of motion is: a) 2/2 s b) 2 s c) 4 s d) V2 s 3. A force of 6.4 N stretches a vertical spring by 0.1 m. The mass that must be suspended from the spring so that it oscillates with a period of second is: 4 kg kg 1 kg 10 kg a) b) c) d) 4 4. In SHM, velocity and acceleration are out of phase (in radians) by: a) b) c) d) 2 4 5. The period of oscillation of molecules is of the order of 10-15s. The corresponding linear and angular frequencies are: a) 1015 Hz & 6.28 x 10-15rad/s b) 10-15 Hz & 6.28 x 1015rad/s c) 10-15 Hz & 6.28 x 10-15rad/s d) 1015 Hz & 6.28 x 1015rad/s 6. Dimensionally the quantity VLC is equal to: a) Frequency b) Time c) Angular frequency d) Inertia 7. Condition for heavy damping is: a) Wo > 2 b) Wo = c) Wo d) wo » - 8. A damped oscillating system which quickly returns to equilibrium position without oscillation is damped: а) Hеavily b) Lightly c) Critically d) Both a & b 9. 2 equals: a) Time period b) Angular frequency c) Angular frequency squared d) Spring constant a 10. If = 10 units, then linear frequency is: а) 10 иnits b) 1.59 units c) 2 units d) 5 units 1.
