The velocityof a body is given by the equation `v = (b)/(t) + ct^(2) + dt^(3)` The dimensional formula of b isA. `[M^(0)LT^(0)]`B. `[ML^(0)T^(0)]`C. `[M^(0)L^(0)T]`D. `[MLT^(-1)]`

Answer» Correct Answer - a
In the equation left hand side has the dimension of velocity .Then the principal of homogenelty each term in the right hand side should have the dimension of velocity `[(b)/(t)] = [v]` or `[b] = [vi] =[L]`
