Question

"Two small masses that are .10m apart attract each other with a force of 10 N. When they are .05 m apart, these masses will attract each other with what force?

a 5.0 N
b 2.5 N
c 20 N

Answer 1

When the two small masses are 0.05m apart, the force between them will be 40 N.

Step-by-step explanation:

The force between two small masses when they are at different distances. This is a physics question that relates to the concept of gravitational force.

According to Newton's law of universal gravitation, the force between two masses is inversely proportional to the square of the distance between them. So, when the distance between the masses is halved (from 0.10m to 0.05m), the force between them will be four times greater. Since the initial force is 10 N, the force when they are 0.05m apart will be 10 N x 4 = 40 N.
