Statement (I) : An object subjected to velocities \(\overrightarrow{v_1}\) and \(\overrightarrow{v_2}\) has a resultant velocity with magnitude \(|\vec{v}|=\left|\overrightarrow{v_1}\right|+\left|\overrightarrow{v_2}\right|\).
Statement (II) : The magnitude of displacement is either less or equal to the path length of an object between two points.
Statement (III) : The instantaneous acceleration is the limiting value of the average acceleration as the time interval approaches zero.
Which of the following is correct?
- A Statements I, II, III are true
- B Statements I, II are true, but Statement III is false
- C Statements II, III are true, but Statement I is false
- D Statements I, II, III are false

Step-by-step Solution
Detailed explanation
\(\mathrm{As}|\mathrm{V}|=\left|\mathrm{V}_1\right|^2+\left|\mathrm{V}_2\right|^2+2\left|\mathrm{~V}_1\right|\left|\mathrm{V}_2\right| \cos \theta\) So (I) is incorrect and, Displacement \(\leq\) Distance So, (II) is correct Also,…
