Question

24.
If pressure P, velocity V and time T are taken as
Pored
fundamental physical quantities, the dimensional
formula of the force is-
(1) PV2T2
(2) P-1V2T-2
(3) PVT
(4) P-IVT​

Answer 1

Answer:

PV²T²

Explanation:

P=F/A

or, F=P×A -----------(I)

we know A=L²

where L=length

then we know

V=L/T

or, L=V×T

then A=V²×T²

Then equation (I) becomes

F=P×V²×T²

or, F=PV²T²
