    By using the equation \[\tan \theta =\frac{rg}{{{v}^{2}}},\]the value of \[\theta \] (angle of banking) for a cyclist taking a curve can be calculated. But the equation is (symbols have their usual meanings)

    A)  dimensionally correct only

    B)  numerically correct only

    C)  both dimensionally and numerically correct

    D)  neither dimensionally nor numerically correct

    Correct Answer: A

    Solution :

                    The given equation is dimensionally correct only because both the sides are dimension less but it is numerically wrong because the correct equation is \[\tan \theta =\frac{{{v}^{2}}}{rg}\]
