Answer:
Dimensions of LHS in all the cases (i) to (iv) = L Dimensions
of RHS in different cases are as follows:.
(i)
(Angle is
dimensionless)
This relation is dimensionally
correct.
(ii)
(Angle is not dimensionless)
This relation is dimensionally
wrong.
(iii)
(Angle is not dimensionless)
This relation is dimensionally
wrong.
(iv)
(Angle is dimensionless)
This relation is dimensionally
correct.
Hence formulae (ii) and (iii) are
dimensionally wrong.
