1.	The period of oscillation of a mass m suspended from a spring of negligible mass is T. If along with it another mass m is also suspended the period of oscillation will now be……..
Answer» `T` `(T)/(sqrt(2))` `2T` `sqrt(2)T` Solution :In first CASE `T= 2pi sqrt((M)/(k))` In second case `T. = 2pi sqrt((M+M)/(k))= 2pi sqrt((2M)/(k))` `therefore (T.)/(T)= sqrt(2)` `therefore T. = sqrt(2)T`.
