a 5-gram pencil
The object that will experience the least amount of gravitational attraction toward Earth is the 5-gram pencil.
To find the object that will experience the least amount of gravitational attraction toward Earth, we need to consider the mass of each object. The formula for gravitational attraction is given by Newton's law of universal gravitation, which states:
F = (G * m1 * m2) / r^2
Where:
F is the gravitational force between two objects
G is the gravitational constant
m1 and m2 are the masses of the objects
r is the distance between the centers of the objects.
Since we are comparing the objects' masses, we can ignore the gravitational constant and the distance between the objects since they are consistent for all objects in this case.
Let's compare the masses of the objects:
- a 75-gram calculator
- a 380-gram cup
- a 40-gram eraser
- a 5-gram pencil
Since we are looking for the object with the least gravitational attraction, we need to find the object with the lowest mass. In this case, the 5-gram pencil has the smallest mass, so it will experience the least amount of gravitational attraction toward Earth.
Therefore, the correct answer is "a 5-gram pencil".
