    Force on the book is 0.25 N

    Explanation:

    • Force is calculated by the equation, F = Mass × Acceleration
    • This is based on Newton’s second law of motion, which states that the force on an object is its mass times the acceleration of the object.

    Here, mass of the book = 50 g = 50/1000 = 0.05 kg (∵ 1 kg = 1000 g)

    Acceleration of the book = 5 m/s²

    ⇒ Force = 0.05 × 5 = 0.25 N
