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.
