If a rubber ball is taken at the depth of 200 m in a pool, its volume decreases by 0.1%. If the density of the water is $1\times {10}^{3}kg/m^3$ and $g=10m/s^2$, then the volume elasticity in  will be

(1) ${10}^8$                                       

(2) $2\times {10}^8$

(3)${10}^9$                                         

(4) $2\times {10}^9$

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

(2) 0.06

(3) 0.02

(4) $19.6\times {10}^{-8}N/m^2$

The Bulk modulus for an incompressible liquid is

(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

(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. \(0.002\)
