Question

h c verma question 73 electrostatics !!!! plz help
find the magnitude of the electric field at the point P in the configuration shown in the figure . take 2qa=p . plz refer book for diagram :) thanks

Answer 1

a)k.q/d^2 ... from basic coulombs law
b)k.2p/d^3 .... from dipole field and along the dipole axis from positive to negative charge
c) it will be the resultant of two perpendicular field k.2p/d^3 from dipole and k.q/d^2 from the positive charge in the center
