#### Write the dimensional formula of a/b in the relation f=a√x+bt2 where f=force,x=distance,t=time.



f = a√x + bt2, where [f] = [M L T −2], [x] = [L] and [t] = [T].

LHS is force. So both the terms on the RHS have the dimensions of force.

[f] = [a&...

#### Write the dimensions of a and b in the relation E=b-x2/at, where E,x and t represent energy,distance and time respectively.



According to the principle of homogeneity of dimensions, [E] = [b] = [(x2/a) t]

[E] = [M L2 T−2]
Therefore [b] = [M L2 T−2

#### which quantity has unit but no dimension?



Angle and solid angle are the physical quantities which have no dimensional formula as they are the ratios of the same physical quantity, but we measure them.
