# The correct statement about Poisson's ratio is:

It is dimensionless

##### SOLUTION
When we apply forces on a body along the length in the opposite directions which are equal in magnitude, it undergoes extension at the same time and contraction along the perpendicular direction.
Within the elastic limits, the ration of lateral strain to the longitudinal strain is called Poisson's ratio and being a ratio it is a dimensionless quantity.
