An aircraft is moving with uniform velocity 150 m/s in the space. If all the forces acting on it are balanced, then it will (a) keep moving with same velocity (b) remain floating at its place (c) escape in space (d) fall down on earth

Answer: (a). Balanced forces mean Fnet = 0, so a = 0 (Newton's first law). With zero acceleration the velocity stays constant at 150 m/s. So the answer is (a) keep moving with same velocity.

An aircraft is moving with uniform velocity $150\text{ m/s}$ in the space. If all the forces acting on it are balanced, then it will

Show answer and solution

Answer: (a)

Balanced forces mean $\vec{F}_{net} = 0$ , so $\vec{a} = 0$ (Newton's first law).
With zero acceleration the velocity stays constant at $150\text{ m/s}$ .
So the answer is (a) keep moving with same velocity.
