#### Answer:

#### Explanation:

By Coulomb's law we Know that force between two charges **Q** and **q** situated at a distance **r** is given by the formula **k** =Coulomb's constant=

Applying this formula the attractive force of 7C on -4C

=

The attractive force of 5C on -4C =

These two forces are oppositely directed so the net force will be towards right and its magnitude
