हिन्दीThe position coordinate of a particle of mass \( m \) moving along the y-axis is given by \( y = ut + \frac{1}{2}gt^2 \). The magnitude of the force acting on the particle is:
View Answer & Solution
Correct answer · Option B
mg
Explanation
Differentiating \( y \) twice with respect to \( t \) yields acceleration \( a = g \). Thus, force \( F = ma = mg \).
