Question

A 2.0-kilogram object is falling freely near Earth's surface. What is the magnitude of the

gravitational force, in Newtons, that Earth exerts on the object?
A) 20
B) 30
c) 10
D) 50

Answer 1

The magnitude of the gravitational force that Earth exerts on a 2.0-kilogram object is 19.6 Newtons.

Step-by-step explanation:

The magnitude of the gravitational force that Earth exerts on an object can be calculated using the formula F = mg, where F is the gravitational force, m is the mass of the object, and g is the acceleration due to gravity (approximately 9.8 m/s² on Earth's surface). In this case, the object has a mass of 2.0 kilograms, so the magnitude of the gravitational force is:

F = (2.0 kg)(9.8 m/s²) = 19.6 N.

Therefore, the correct answer is A) 20 Newtons.
