Will two point charges, each with a charge of +1 Coulomb and separated by a distance of 1 meter, attract or repel?

Answer 1

The force of two charges of +1C each at a distance of 1 m would be about 9x10^9 N and repulsive; unlike charges, like charges attract.

Coulomb's law, which states that force is proportional to the product of charges, makes this clear.

The resultant of the product can be either a (-) or a (+) because charges can be positive or negative.

Therefore, the force is attractive if the product resultant is negative and repulsive if it is positive.

The two point charges with the same sign (+1 Coulomb) will repel each other.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
