On the basis of dimensional, decide which of the following relation for the displacement of a particle undergoing simple harmonic motion is not correct :

Options

A. `y = a sin 2 pi t//T`
B. `y =a sin upsilon t`
C. `y = (a)/(y) sin((t)/(a))`
D. `y= a sqrt2(sin(2pit)/(T) - cos(2pit)/(T))`

Answer

(b,c)

Explanation

As angle is dimensionless, therefore, choice (b) and (c ) are not correct.
