Answer 2

Answer:

Expression for the electric field intensity due to a point charge :

Let a point charge q is placed at distance r and put a test charge where we have to find  E intensity :

  + q                                                     > q₀  .. p

                               r                          

Electric field is equal to force on test charge upon test charge.

E = F / q₀

E_p = ( k q q₀ / r² ) / q₀

E_p = k q / r²

= > E = k q /  r²

Therefore we get required expression.
