PhysicsEasyassertion reason

Assertion: Velocity, volume and acceleration can be taken as fundamental quantities

Reason: All the three are independent from each other.

Options:

Answer:

Solution:

Both statements are wrong.
The three are NOT independent:
$\frac{L ^{3} \times ( L T ^{- 2} ) ^{3}}{( L T ^{- 1} ) ^{6}}$
$= \frac{L ^{6} T ^{- 6}}{L ^{6} T ^{- 6}}$
$= L^{0} T^{0}$
is dimensionless, so they cannot all be fundamental;
the Reason is therefore also false.
