(a) Two-point charges with equivalent charge of q are placed at (L,0,0) and (-L,0,0). (1) Show that the total electric field E at (0,0,z) is q Etotal = 3 (za₂) 2περ{Vzz + [3) (ii) Using Coulomb's law, calculate the force F acting on another point charge Q at (0,0,z). (iii) Determine the value of z when the force F is maximum. d dB(x) (Hint: A(x). B(x) = A(x) + B(x) (x)) dx dx
