Question

Let x = πR`(("P"^2 - "Q"^2)/2)`, where P, Q and Rare lengths. The physical quantity x is ______.

Options

• area

• length

• volume

• velocity

Answer 1

Let x = πR`(("P"^2 - "Q"^2)/2)`, where P, Q and Rare lengths. The physical quantity x is volume.

Explanation:

Given, x = πR`(("P"^2 - "Q"^2)/2)`

where, P, Q and Rare lengths.

So, units of P, Q and Rare meter.

∴ Unit of x = m³

Which is unit of volume.
