What is the weight, on Earth, of a book with a mass of 1.5 kg? 1.5 N 6.5 N 11.3 N 14.7 N
alexira [117]

The rigth answer is 14.7N

The law of gravitation thus makes it possible to calculate a force exerted between two objects. In a terrestrial reference system, we can then calculate the force exerted between the Earth and an object.

The law applied in this case is P = mass x g (gravitational constant = 9.8 N / kg)

if a book weighs 1.5 kg then: P = 1.5 x 9.8 = 14.7N

So it's between B and C, I am leaning towards B.
