When a pressure of 100 atmosphere is applied on a spherical ball, then its volume reduces by 0.01%. The bulk modulus of the material of the rubber in $dyne / c{m}^2$ is:

1. $10\times {10}^{12}$                               

2. $100\times {10}^{12}$

3. $1\times {10}^{12}$                                 

4. $20\times {10}^{12}$

A uniform cube is subjected to volume compression. If each side is decreased by 1%, then bulk strain is

1. 0.01                             

2. 0.06

3. 0.02                             

4. 0.03

A ball falling in a lake of depth 200 m shows 0.1% decrease in its volume at the bottom. What is the bulk modulus of the material of the ball

1. $19.6\times {10}^{8}N/m^2$               

2. $19.6\times {10}^{-10}N/m^2$

3. $19.6\times {10}^{10}N/m^2$               

4. $19.6\times {10}^{-8}N/m^2$

The Bulk modulus for an incompressible liquid is

1. Zero                                           

2. Unity

3. Infinity                                       

4. Between 0 to 1

The ratio of lengths of two rods $A$ and $B$ of the same material is $1:2$ and the ratio of their radii is $2:1$. The ratio of modulus of rigidity of $A$ and $B$ will be:

When a spiral spring is stretched by suspending a load on it, the strain produced is called:

The Young's modulus of the material of a wire is $6\times 10^{12}~\text{N/m}^2$ and there is no transverse strain in it, then its modulus of rigidity will be:

1. $3\times 10^{12}~\text{N/m}^2$
2. $2\times 10^{12}~\text{N/m}^2$
3. $10^{12}~\text{N/m}^2$
4. None of the above

Modulus of rigidity of a liquid:

1. Non zero constant

2. Infinite

3. Zero

4. Can not be predicted

A cube of aluminium of sides $0.1~\text{m}$ is subjected to a shearing force of $100$ N. The top face of the cube is displaced through $0.02$ cm with respect to the bottom face. The shearing strain would be:
1. $0.02$                                   
2. $0.1$
3. $0.005$                               
4. $0.002$
