NEET Physics Equations of Motion MCQ Question
Type: MCQ-numerical-Medium-Class 11
A body with mass 5 kg is acted upon by a force F = (−3î + 4ĵ)N. If its initial velocity at t = 0 is v = (6î − 12ĵ) ms⁻¹, the time at which it will just have a velocity along the Y⁻axis is
A
Never
B
10 s
C
2 s
D
15 s
Correct Answer
Option C
Detailed Explanation
The force causes an acceleration, changing the velocity over time. Solving the equations of motion, the velocity along the X⁻axis becomes zero at 2 seconds.
