NEET 2024 Physics Dimensionless Quantities MCQ Question
A force defined by F = αt² + βt acts on a particle at a given time t. The factor which is dimensionless, if α and β are constants, is:
αβt
αβ/t
βt/α
αt/β
Correct Answer
Detailed Explanation
To find a dimensionless quantity, the dimensions of the numerator and denominator must cancel out. Here, βt/α is dimensionless because the dimensions of βt (force) and α (force/time²) cancel out.
