Q2. A body of mass 2.0 kg and radius of gyration 0.5 m is rotating about an axis. If its angular speed is 2.0 rad/s, the angular momentum of the body (in kg -

m^{2}

/s) is

A. 2.0

B. 0.5

C. 1.5

D. 1.0

Answer : Option D
Explaination / Solution:

$\begin{aligned} I = m k^{2} \\ m = 2 K g \\ k = 0.5 m \\ I = 2 \times 0.5 \times 0.5 = 0.5 K g m^{2} \end{aligned}$

angular momentum

$\begin{aligned} L = I ω \\ ω = 2 r a d / s \\ L = 0.5 \times 2 = 1.0 K g m^{2} / s \end{aligned}$

C. It will remain on it as a sphere

D. It will float as a distorted drop on the water surface

Answer : Option A
Explaination / Solution:

when any liquid is poured onto another liquid there are different phenomena that can take place depending on the properties of liquids:In case of crude oil and water - The two liquids are non-miscible and the first is lighter than the second. The first liquid then spreads on the surface of the second liquid forming a thin layer. The thickness of this layer depends on the properties of the two liquids. This is the case for most hydrocarbons, including both refined products and crude oil of API gravity greater than 10.
