The correct order in which the dimensions of "length" decreases in the following physical quantities is
a) Coefficient of viscocity 
b) Thermal capacity
c) Escape velocity
d) Density


ANSWER

b, c, a, d


SOLUTION
a) Coefficient of viscosity $$=\dfrac{MLT^{-2}\times L}{\left ( L^{2} \right )\left ( LT^{-2}\right )}=ML^{-1}T^{-3}$$
b) Thermal capacity $$=ML^{2}T^{-2}T^{-1}\rightarrow $$(temperature)
c) Escape velocity 
$$=LT^{-2}$$
d) Density $$=ML^{-3}$$
So, dimension of length in $$b>c>a>d$$.
