What is the acceleration produced by a force of 0.5N applied on a body of mass 0.1 kg?
Correct answer: D. 5 ms-2
- A. 0.1 ms-2
- B. 0.5 ms-2
- C. 1 ms-2
- D. 5 ms-2
Explanation
To determine the acceleration, use Newton's Second Law of Motion, which states F = ma. Rearranging gives a = F/m.Insert the given values: F = 0.5 N and m = 0.1 kg. Therefore, a = 0.5 N / 0.1 kg = 5 ms-2.Hence, the correct answer is 5 ms-2. The other options are incorrect due to errors in calculation or application of the formula, such as incorrect division or substitution.

About Force and Motion
Displacement, velocity and acceleration describe motion, including the horizontal and vertical components of projectile motion. The chapter connects these quantities with Newton's laws, momentum and impulse, then applies conservation of momentum to collisions, distinguishing elastic collisions from inelastic ones.
