QNEET-2024-Ph-62: NEET 2024 Physics - Class 11 NEET-2024-Ph-62 Solution: At any instant of time t the displacement of any particle is…

Core Concept & Governing Formula(s): Instantaneous power delivered by a force is the scalar product of the force vector and the velocity vector of the particle: When force and motion are along the same line, the vectors can be treated as scalars and the formula reduces to $P = F\,v$. Step 1: Determine the velocity of the particle. The displacement is given as a function of time: Velocity is the time derivative of displacement: Thus the particle moves with a constant velocity of $2\ \text{m s}^{-1}$. Step 2: Use the given constant force. The force acting on the particle is $F = 5\ \text{N}$. Since the direction of the force is along the direction of displacement, we can treat it as a scalar. Step 3: Compute the instantaneous power. Apply $P = F\,v$: Final Conclusion & Correct Option: The instantaneous power at any instant $t$ is $10\ \text{W}$. Correct option: **A) 10**.
