CHAPTER 1: ELECTRIC CHARGES AND FIELDS

🔺ELECTRIC CHARGE

           Electric charge is the physical property of matter that causes it to experience a force when placed in an electromagnetic field.

→There are two types of charge

    a. Positive charge           b. negative charge

→Unit of charge

    S.I Unit-coulomb(C)

→Properties of charge

   a. charges are additive

   b.charge is conserved

   c. charge is quantized

   *charge on one electron(e)=1.6x10^(-19) C

🔺COULOMB'S LAW

         If two charges with magnitude q1 and q2 are separated by a distance r then force between them is
