Question

You push on a crate that sits on a smooth floor, and it accelerates. If you apply four times the net force, then the acceleration will be

• A. twice
• B. thrice
• C. equal
• D. four times

Answer 1

The correct option is D four times

From Newton's IInd law of motion $F_{net}=ma$ the acceleration is directly proportional to force applied.
Frictional force is zero in the problem $F_{net}=$ applied force
Thus by increasing the applied force to four times, acceleration will also increase to $4$ times.
