" The relation II is "

A circular railway track of radius r is banked at angle theta so that a train moving with speed v can safely go round the track. A student writes: tan theta =rg//v^(2) . Why this relation is not correct? (i) Equality of dimensions does not guarantee correctness of the relation . (ii) Dimensionally correct relation may not be numerically correct. iii) The relation is dimensionally incorrect.
