1.	Give the expression for frequency of oscillation of a mass body as shown in the fig.
Answer» Solution :EFFECTIVE spring constant `=(1)/(K)=(1)/(k_(1)+k_(2))+(1)/(k_(3))` `"i.e."(1)/(k)=((k_(1)+k_(2)+k_(3)))/((k_(1)+k_(2))k_(3))` Period of OSCILLATION `T=2pi sqrt(m((k_(1)+k_(2)+k_(3)))/((k_(1)+k_(2))k_(3)))` SINCE frequency of oscillation `n=(1)/(T)=(1)/(2pi)sqrt(((k_(1)+k_(2))k_(3))/(m(k_(1)+k_(2)+k_(3))).`
