Question
b) A 50.0 gm object connected
with an amplitude of 4.0 cm on a frictionless, horizontal surface. Find
i) the total energy of the system.
ii) the speed of the object when its position is 1.0 cm.
iii) kinetic energy and potential energy when its position is 3.0 cm.
a) What are forced vibrations? Examine the effect of a periodic force on the motion of a
damped oscillator.
2.
b) The amplitude b of forced vibration in a mechanical system is given by
fo
[(m-@?)² + 4r²oz
Show that for
i) o<< @o, the response is independent of the mass,
ii) for o = Oo, the amplitude at resonance depends inversely on the damping constant
r and
im) for o >> 0o, the response is independent of the spring constant of the system.

derive the expression for bright and dark fringes.
b) In Michelson's interferometer a thin plate is introduced in the path of one of the beams
and it is found that 50 band crosses the line of observation. If the wavelength of light
