The dimensional formula for impulse is
- A \(\left[\mathrm{MLT}^{-1}\right]\)
- B \(\left[\mathrm{ML}^{-1} \mathrm{~T}\right]\)
- C \(\left[\mathrm{M}^{-1} \mathrm{LT}^{-1}\right]\)
- D \(\left[\mathrm{ML}^{-1} \mathrm{~T}^{-1}\right]\)
Answer & Solution
Correct Answer
(A) \(\left[\mathrm{MLT}^{-1}\right]\)
Step-by-step Solution
Detailed explanation
Impulse \(=\) force \(\times\) time \(=\left[\mathrm{MLT}^{-2}\right][\mathrm{T}]\)
\(=\left[\mathrm{MLT}^{-1}\right]\)
\(=\left[\mathrm{MLT}^{-1}\right]\)
