When force of 1 N is applied on a body of mass 100 g then the acceleration would be

Correct answer: B. 10 m s-2

  • A. 5 m s-2
  • B. 10 m s-2
  • C. 0.5 m s-2
  • D. 0.1 m s-2

Explanation

To find the acceleration, use Newton's second law, which states that Force = Mass × Acceleration (F = ma). First, convert the mass from grams to kilograms: 100 g = 0.1 kg. Then, use the formula with the given force: 1 N = 0.1 kg × acceleration. Solving for acceleration gives acceleration = 1 N / 0.1 kg = 10 m s-2. Therefore, Option B is correct. The other options are incorrect due to either incorrect formula application or failure to convert units properly.

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.
