Question 103: Properties of Matter

Question

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 :

Accepted Answer

[Pressure][Time] = $$\left[ {{{Force} \over {Area}}} ight]$$$$\left[ {{{distance} \over {Area}}} ight]$$
[Coefficient of viscosity] = $$\left[ {{{Force} \over {Area}}} ight]$$$$\left[ {{{distance} \over {Area}}} ight]$$
Statement 'A' is true
But Statement 'R' is false are coefficient of viscosity
$$ = {{Force} \over {Area 	imes Velocity\,gradient}}$$

Answer

Both A and R are true, and R is the correct explanation of A.

Answer

Both A and R are true but R is NOT the correct explanation of A.

Answer

A is true but R is false.

Answer

A is false but R is true.
