NEET (UG) 2024 — Question 4

At any instant of time tt, the displacement of any particle is given by 2t−12 t-1 (SI unit) under the influence of force of 5 N . The value of instantaneous power is (in SI unit):

  1. Option A:

    10

    Correct
  2. Option B:

    5

  3. Option C:

    7

  4. Option D:

    6

Answer: A

Step-by-step solution

x=2t−1x=2 t-1

v=dxdt=2 m s−1v =\frac{d x}{d t}=2 \mathrm{~m} \mathrm{~s}^{-1}

P=F⋅vP =F \cdot v

=2×5=10 W =2 \times 5=10 \mathrm{~W}
