Final answer:
The mass of a 1.2 N book is obtained by dividing the force by the acceleration due to gravity. Using the formula m = F / g, the mass is calculated to be approximately 0.122 kilograms.
Step-by-step explanation:
To find the mass of a book that has a force (weight) of 1.2 N, we use the relationship between force, mass, and acceleration due to gravity. The equation is F = m × g, where F is the force in newtons, m is the mass in kilograms, and g is the acceleration due to gravity, which is approximately 9.8 m/s2 on Earth’s surface.
Rearranging the equation to solve for mass, we get m = F / g. Plugging in the values, the mass m is 1.2 N / 9.8 m/s2 = 0.122 kg. So, the mass of the book is approximately 0.122 kilograms.
