Question

If two objects are positive and negative, how does changing the distance between affect the force between them?

a) The force increases as the distance increases.
b) The force decreases as the distance decreases.
c) The force decreases as the distance increases.
d) The force increases as the distance decreases.

Answer 1

The force between two positve and negative objects decreases as the square of the distance between them increases.

Step-by-step explanation:

In the case of two objects with opposite charges, the force between them depends on the distance between them. Experimentally, it has been found that the magnitude of the force decreases as the square of the distance increases. This means that if you double the distance between the objects, the force between them decreases to one fourth of its original value. On the other hand, if you decrease the distance by a factor of 1/10, the force will increase by a factor of 100.
