The correct dimensional formula for impulse is given by
- A \(\mathrm{ML}^{2} \mathrm{T}^{-2}\)
- B MLT \(^{-1}\)
- C \(\mathrm{ML}^{2} \mathrm{T}^{-1}\)
- D \(\mathrm{MLT}^{-2}\)
Answer & Solution
Correct Answer
(B) MLT \(^{-1}\)
Step-by-step Solution
Detailed explanation
As we know that, Impulse, \(I=\) force \((F) \times\) small time interval \(\begin{array}{ll} I=m a \times t & {[\because F=m a]} \\ I=[\mathrm{M}]\left[\mathrm{LT}^{-2}\right] \times[\mathrm{T}] \\ I=\left[\mathrm{MLT}^{-1}\right] \end{array}\) Hence, the correct dimensional…
