• Coulomb's Law: The force of attraction or repulsion between two point charges is directly proportional to the product of the magnitude of charges and inversely proportional to the square of the distance between them.
• Important class 10th physics chapter 13 important questions for all students of Punjab  Textbook Board.
• Electric field and electric field intensity: According to Coulomb's law if a unit positive charge q call it a test charge is brought near a charge q (call it a field charge) placed in space, the charge q will experience a force.
• Important 10th class physics chapter 13 pdf for all students of Punjab  Textbook Board.
•  The value of this force depends upon the distance between the two charges. If the charge q is moved away from q, this force would decrease till at a certain distance the force would be practically reduced to zero. The charge q is then out of the influence of charge q. 
• Important 10th class physics chapter 13 short questions for all students of Punjab  Textbook Board.
• The region of space surrounding the charge q in which it exerts a force on the charge q is known as electric field of the charge q. Thus, the electric field of a charge is defined as:
• "The electric field is a region around a charge in which it exerts electrostatic force on another charges".
• Important 10th class physics chapter 13 notes for all students of Punjab  Textbook Board.
• Electric Field Intensity:  The strength of an electric field at any point in space is known as electric field intensity. In order to find the value of electric intensity at a point in the field, of charge +q, we place a test charge q at that point. If F is the force acting on the test charge q, the electric field intensity would be given by   E = F / q
• Important 10th class physics chapter 13 mcqs for all students of Punjab  Textbook Board.
• "The electric field intensity at any point is defined as the force acting on a unit positive charge placed at that point". 
• SI unit of electric intensity is N C^-1.
• Important 10th class physics chapter 13 numericals solved for all students of Punjab  Textbook Board.
• If the electric field due to a given arrangement of charges is known at some point, the force on any particle with charge q placed at that point can be calculated by using the formula:  F = qE
• Important 10th class physics chapter 13 numerical for all students of Punjab  Textbook Board.
• Electric intensity being a force is a vector quantity. Its direction is the same as that of the force acting on the positive test charge. If the test charge is free to move, it will always move in the direction of electric intensity.
• Important 10th class physics chapter 13 numericals solved pdf for all students of Punjab  Textbook Board.
• Electric Field Lines: The direction of electric field intensity in an electric field can also be represented by drawing lines. These lines are known as electric lines of force. These lines were introduced by Michael Faraday. 
• Important physics class 10 chapter 13 review questions notes for all students of Punjab  Textbook Board.
• The field lines are imaginary lines around a field charge with an arrow head indicating the direction of force. Field lines always directed from positive charge are towards negative charge. The spacing between the field lines shows the strength of electric field.
