A constant force acts on a body of mass 10 kg and produces in it an acceleration of 0.2 m s^–2. Calculate the magnitude of force acting on the body.

Given Mass = 10 kg

a = 0.2 ms⁻²

∴ Force = mass × acceleration (F = ma)

∴ F = (10 kg) × (0.2 m s⁻²) = 2 N

Thus, the magnitude of force acting on the body is 2 N.
