1) Electric force: Electric force is the force that exists between two charged objects. Like charges repel each other, while opposite charges attract each other. The strength of the electric force depends on the amount of charge on the objects and the distance between them. The formula for electric force is given by Coulomb's law: F = k * (q1 * q2) / r^2, where F is the electric force, k is the electrostatic constant, q1 and q2 are the charges of the objects, and r is the distance between them.
Example: When you rub a balloon on your hair, the balloon becomes negatively charged and your hair becomes positively charged. The electric force between the balloon and your hair causes them to stick together.
2) Electric field: An electric field is a region around a charged object where another charged object will experience an electric force. The electric field is a vector quantity, meaning it has both magnitude and direction. The strength of the electric field is determined by the amount of charge on the object creating the field and the distance from the object. The formula for electric field is given by E = F / q, where E is the electric field, F is the electric force, and q is the charge experiencing the force.
Example: When you bring a positively charged object near a negatively charged object, the positively charged object will experience an electric force due to the electric field created by the negatively charged object. This force will cause the positively charged object to move towards the negatively charged object.
Example: When you rub a balloon on your hair, the balloon becomes negatively charged and your hair becomes positively charged. The electric force between the balloon and your hair causes them to stick together.

1. Electric Force
- Definition: Electric force is the interaction between two charged particles. The force can be either attractive (between oppositely charged particles) or repulsive (between like-charged particles).
- Formula: F = k - (q1 - q2) / r^2, where:
- F is the electric force
- k is Coulomb's constant (8.988 x 10^9 N m²/C²)
- q1 and q2 are the charges of the particles
- r is the distance between the particles
- Examples:
- The attraction between electrons and protons in an atom
- The repulsion between two positively charged ions
- The electrostatic force between a negatively charged balloon and your hair
2. Electric Field
- Definition: Electric field is a region of space around a charged particle where other charged particles experience an electric force. The electric field is created by the presence of the charged particle.
- Formula: E = k - q / r^2, where:
- E is the electric field
- k is Coulomb's constant
- q is the charge creating the electric field
- r is the distance from the charge to the point in space where the electric field is being measured
- Examples:
- The electric field around a charged wire
- The electric field between the plates of a capacitor
- The electric field around a charged comb
