Physics · JEE | SYSTEMS OF PARTICLES AND ROTATIONAL MOTION
हिन्दीNewton's second law of motion extended to a system of particles relates the time derivative of total linear momentum \( \frac{d\mathbf{P}}{dt} \) to which of the following forces?
View Answer & Solution
Correct answer · Option B
Sum of all external forces \( \mathbf{F}_{\text{ext}} \)
Explanation
Differentiating \( \mathbf{P} = M\mathbf{V} \) gives \( \frac{d\mathbf{P}}{dt} = M\mathbf{A} = \mathbf{F}_{\text{ext}} \).
