हिन्दीAt any instant of time \( t \), the displacement of any particle is given by \( 2t - 1 \) (SI unit) under the influence of force of \( 5\text{ N} \). The value of instantaneous power is (in SI unit):
Correct answer · Option 3
10
Explanation
Velocity \( v = \frac{dx}{dt} = \frac{d}{dt}(2t - 1) = 2\text{ m/s} \). Instantaneous power \( P = F \cdot v = 5 \times 2 = 10\text{ W} \).
