Question

( begin{aligned} a &=(P)left(v^{2}right) &=frac{m L T^{-2}}{1^{2}} L^{6} &=m L^{5} T^{-2}(1) end{aligned} )

# The equation of state of some gases can be expressed as P+ 2 (V - b) = RT , where P is the pressure, V is the volume, T is the absolute temperature and a, b & R are constants. The dimensions of 'a' are :- (1) [ML5 T-21 (2) [M L-11-21 (3) [L] (4) [L]
