Answer (2)
The mutual forces of gravity between the Earth and an object on or near its surface are ( mass of the object ) x ( acceleration of gravity on Earth ). These two forces are equal, and we call their strength the "weight" of the object. It's the number shown on the scale as long as nobody has their thumb on the scale. In this problem, the force is 45N . (That's about 10.12 pounds.)
The acceleration of gravity on Earth is about 9.8 meters per second² .
So 45N = (mass in kilograms) x (9.8 meters per second²)
Divide each side by 9.8 : Mass = 45/9.8 = 4.59 kilograms (rounded)
The mass of an object exerting a force of 45 N on a spring scale is approximately 4.59 kg. This is calculated using the formula m = g w with g being 9.81 m/s². The spring scale's reading directly reflects the weight of the object in newtons.
