Correct Answer - Option 2 : -5Q

Correct option - 2

Concept:

  • Electric charge is the basic physical property of matter that causes it to experience a force when kept in an electric or magnetic field.
  • An electric charge is associated with an electric field and the moving electric charge generates a magnetic field.
  • A combination of electric and magnetic fields is known as the electromagnetic field.
  • Interaction of the charges generates an electromagnetic force which is the foundation of Physics.


The two types of electric charges are:

1. Positive

2. Negative

Calculation:

Given-

Charges on the system = +Q, -2Q, +Q and -5Q.

Charge on the system will show the additive nature.

i.e Net or total charge on the system = sum of all the charges enclosed by the system.

so, QT = (+Q) + (-2Q) + Q + (-5Q)

⇒ QT = +2Q - 2Q - 5Q

∴ QT = -5Q

Hence, option - 2 is correct
