Question

A test tube of mass 6 g and uniform area of cross section 10 ~cm ^2 is floating in water vertically when 10 g of mercury is in the bottom. The tube is depressed by a small amount and then released. The time period of oscillation is ( . Acceleration due to gravity =10 ~ms ⁻² )

Correct answer: C. 0.25 s

aligned & m =6+10=16 ~g =0.016 ~kg & k = F x = Axg x = ^ A ~g =10^3 10 10⁻⁴ 10 & =10 Nm ⁻¹ aligned Time period, T =2 ~m k =2 0.016 10 = 2 4 100
