Q13 of 44 Page 7

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

Dimensional formula of displacement =


From study of dimensional analysis we know that,


Numbers have no dimension.


Trigonoetric functions are dimensionless.


Constants are dimensionless.


According to above rules


Dimension of


Dimension of


Dimension of


Dimension of


So, only option is C that doesn’t have dimension that of displacement.
