A student named Brandy was asked to calculate the mass of four objects. After finding the mass of the objects, Brandy made a table to help keep her work organized. Her teacher then asked her the following question: "Based on the mass of the objects you listed, which object is Earth's gravity acting on the LEAST?"

Brandy's Table:

Object Mass (g)
1 100
2 150
3 200
4 50

To determine which object Earth's gravity is acting on the least, Brandy should calculate the weight of each object using the formula:

Weight = mass x gravity

Since all objects are on Earth, the acceleration due to gravity is 9.8 m/s^2.

Calculating the weight for each object:

1. Object 1: 100g x 9.8 m/s^2 = 980 N
2. Object 2: 150g x 9.8 m/s^2 = 1470 N
3. Object 3: 200g x 9.8 m/s^2 = 1960 N
4. Object 4: 50g x 9.8 m/s^2 = 490 N

Based on these calculations, Object 4 is experiencing the least amount of force from Earth's gravity.
