Properties of electric field
Strength of electric field
Mathematical expression

4. ELECTRIC FIELD:
 The region around the electric charge where the electric force
acts is called an electric field
 It is represented by symbol E.

5. PROPERTIES OF ELECTRIC FIELD:
 It is present around a charge weather other charges are present
or not>
 It is a force field which exerts a force on other charges placed in
its region.
 It is represented by imaginary lines of force.
 For positive charge lines will come out of the charge.
 For negative charge lines will move towards the charge.
 The number of lines is directly propotional to the strength of
electric field.

6. Field lines move out of the positive charge.
Field lines move towards the negative charge.

7. INTERACTION BETWEEN CHARGES:
Unlike charges(attraction): Like charges(repulsion):

8. STRENGTH OF ELECTRIC FIELD:
Strength of C is the highest because strength is directly propotional to the no. of lines

10. MATHEMATICAL EXPRESSION:
