The net force on the -4.0μC object as a result of this net field will be -10.4 N.
<h3>What is the charge?</h3>
The matter has an electric charge when it is exposed to an electromagnetic field is known as a charge.
The electric field intensity is found as the force per unit charge.
Electric field intensity on the positive charge:

Electric field intensity on the negative charge:

The net charge is the algebraic sum of the two charges;

Hence, as a result of this net field, the net force on the -4.0C object will be -10.4 N.
