Question
In which situation is the gravitational force between two objects hard to detect? A. if the objects are very close together B. if the mass of one of the objects is very great C. if the mass of each object is very small D. if the mass of both objects is very great
Solution
The gravitational force between two objects is hard to detect in situation C. if the mass of each object is very small.
Here's why:
Gravitational force is determined by the formula F = G * (m1*m2)/r^2, where F is the gravitational force, G is the gravitational constant, m1 and m2 are the masses of the two objects, and r is the distance between the centers of the two objects.
A. If the objects are very close together, the gravitational force would actually be stronger because the distance r in the denominator of the formula is smaller.
B. If the mass of one of the objects is very great, the gravitational force would be stronger because m1 or m2 in the numerator of the formula is larger.
C. If the mass of each object is very small, the gravitational force would be weaker because m1 and m2 in the numerator of the formula are smaller. This makes it harder to detect.
D. If the mass of both objects is very great, the gravitational force would be stronger because m1 and m2 in the numerator of the formula are larger.
