Question

If density D, frequency F and velocity V are taken
as fundamental quantities then the dimensional
formula for kinetic energy should be E M ET
(1) [DF-3V5] (2) [D-2F2V-31
(3) [D-3F5V]
(4) [DFV-3)​

Answer 1

Answer:

the dimensional formula for kinetic energy is M1L2T-2

D=[M1L-3]

V=[LT-1]

F=[T-1]

KE=D^aV^bF^c

equate the dimensional formula on both sides
