The velocity of a body is given by the equation `v= b//t+ ct^(2) + dt^(3)`. Find the dimensional formula for b.

Text Solution

Verified by Experts

By the principle of homogeneity, `a//V^(2)` is of the dimensions of pressure  and b is of the dimensions of volume.
[a] = [pressure] `[V^(2)]= [ML^(-1) T^(-2)] [L^(6)]= [ML^(5)T^(-2)]`
[b] `=[V]= L^(3)`
