Answer: 0.25N
Explanation:
Given that
mass of book = 50 grams
Convert mass in grams to kilograms
If 1000 grams = 1 kg
50 grams = (50/1000) = 0.05 kg
acceleration = 5 m/s/s
Force on the book = ?
Since force is the product of mass of an object and the acceleration by which it moves.
i.e Force = mass x acceleration
force = 0.05kg x 5 m/s/s
Force = 0.25N
Thus, the force on the book is 0.25Newton
