Out of the formulae y =a sin `2pi t//T` and y = a sin `upsilon t` for the displacement y of particle undergoing a periodic motion, rule out the wrong formula on the basis of dimensions. Symbols have standard meaning.

Out of formula (i) y=a sin2 pi t//T and(ii)y=a sin vt for the displacement y of a pratice undergoing a certain peripdic motion, rule out the wrong formula on dimesional ground.

If the displacement y of a particle is y =A sin (pt+qx) then dimensional formula of pq is

If the displacement y of a particle is y =A sin (pt+qx) then dimensional formula of pq is

A book with many printing errors contains four different formulas for the displacement y of a particle undergoing a certain periodic motion :- y=a sin 2pi t//T (a = maximum displacement of the particle, v = speed of the particle. T= time-period of motion). Rule out the wrong formulas on dimensional grounds.
