Fundamental quantities – Rankers Physics

Units: Practice Problem & Solution

Assertion (A): Mass, length and time may be taken as fundamental quantities. Reason (R): Mass, length and time are independent of one another.  
Both (A) & (R) are true and the (R) is the correct explanation of the (A)
Both (A) & (R) are true but the (R) is not the correct explanation of the (A)
(A) is true but (R) is false
Both (A) and (R) are false

Short Solution (Best for NEET):

To solve this problem, we apply the core principles of Units. Understanding the underlying formula is key to arriving at the correct answer below:

Mass, length, and time are chosen as fundamental quantities because they are independent of each other and cannot be defined in terms of one another.
