নিচের কোনটি দুরত্বের একক নয়?  

$\left ( P + \frac{a}{V^{2}} \right ) \left ( V - b \right ) = R T$   সমীকরণটিতে a এর মাত্রা কত?

The Van der Waal's equation of state for some gases can be expressed as:

$(P + \dfrac{a}{V^2})(V - b) = RT$

where P is the pressure, V is the molar volume, and T is the absolute temperature of the given sample of gas and a,b and R are constants.

The dimensions of a are

The dimensional formula for impulse is same as the dimensional
