NEET Physics Physical Quantities Assertion Reason Question
Assertion (A): Dimensional analysis can help determine the numerical value of constants in an equation.
Reason (R): Dimensional analysis can test the dimensional validity of equations but cannot distinguish between physical quantities with the same dimensions.
Both A and R are true, and R is the correct explanation of A.
Both A and R are true, but R is not the correct explanation of A.
A is true, but R is false.
A is false, but R is true.
Correct Answer
Detailed Explanation
The NCERT context states that dimensional analysis cannot obtain dimensionless constants, while R correctly describes a limitation of dimensional analysis.
