Given below are two statements : One is labelled as Assertion A and the other is labelled as Reason R.
Assertion A : Product of Pressure (P) and time (t) has the same dimension as that of coefficient of viscosity.
Reason R : Coefficient of viscosity = ${{Force} \over {Velocity\,gradient}}$
Choose the correct answer from the options given below :
Solution
<p>[Pressure][Time] = $\left[ {{{Force} \over {Area}}} \right]$$\left[ {{{distance} \over {Area}}} \right]$</p>
<p>[Coefficient of viscosity] = $\left[ {{{Force} \over {Area}}} \right]$$\left[ {{{distance} \over {Area}}} \right]$</p>
<p>Statement 'A' is true</p>
<p>But Statement 'R' is false are coefficient of viscosity</p>
<p>$= {{Force} \over {Area \times Velocity\,gradient}}$</p>
