The relation between force '$$F$$' and density '$$d$$' is $$F=\displaystyle\frac{x}{\sqrt{d}}$$. The dimensions of $$x$$ are:

Which one of the following pair of quantities has same dimension?

Dimensions $$[ML^{-1}T^{-1}]$$ are related to

If acceleration ($$A$$), mass ($$M$$), velocity ($$V$$), time ($$T$$) are the fundamental units, then the dimensions of height will be

The dimension of universal gravitational constant is :

The pressure on a square plate is measured by measuring the force on the plate. If the maximum error in the measurement of force and length are respectively $$4\%$$ and $$2\%$$, then the maximum error in the measurement of pressure is :
