Aglass rod with a net charge of 0.748 μc and a small square of silk cloth with a net charge of −0.502 μc, are separated by 12.0 cm.
what is the magnitude of the attractive force between the two charged objects? you may approximate both objects as point charges.

Two positive charge  will produce force of of 0.23 N and negative sign shows that the force between charges is attractive.

Explanation:

Given that,

Net charge on a glass rod,

Net charge on a silk cloth,

Separation between charges, d = 12 cm = 0.12 m

To find,

The magnitude of the attractive force between the two charged objects.

Solution,

If F is the electric force between two charges. It is given by the electrostatic force of attraction. It is given by :

So, two positive charge  will produce force of of 0.23 N and negative sign shows that the force between charges is attractive.
