NEET 2013 Physics Motion in One Dimension MCQ Question
The displacement 'x' (in metre) of a particle of mass 'm' (in kg) moving in one dimension under the action of a force, is related to time 't' (in sec) by t = √x + 3. The displacement of the particle when its velocity is zero, will be:
4 m
0 m (zero)
6 m
2 m
Correct Answer
Detailed Explanation
Velocity is zero when dx/dt = 0. Differentiate the given equation with respect to time and solve for x when velocity is zero.
