Charges of −5.3 µC and +5.3 µC are separated by 4.2 cm. Find the electric force between them.

Force between two charges is given as 143.3 N

Explanation:

As we know that electrostatic force between two point charges is given as

here we know that

also we know that

so we have

so we have

current and voltage can both be different in different parts of a circuit so it matters where you place the ammeter and voltmete

i think it would be 5
