Question

Density 'D' velocity 'V', Acceleration 'A'
are taken as fundamental units, then
dimensioned formula of mass is
D'VnA-3 then n=​

Answer 1

Answer:

Here is the solution

Explanation:

Correct option is

D

DV

4

F

−3

Momentum =[F]

a

[V]

b

[D]

c

⟹[MLT

−1

]=[T

−1

]

a

[LT

−1

]

b

[ML

−3

]

c

Comparing both sides,

c=1

b−3c=1

∴b=4

Also,

a+b=1

∴a=−3

Therefore,

Momentum =[F]

−3

[V]

4

[D]
