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 1 (119.38 KiB) Viewed 16 times

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 (zaz) 2περ{Vz2 + 12) (ii) Using Coulomb's law, calculate the force F acting on another point charge Qat (0,0,z). (iii) Determine the value of z when the force F is maximum. + B(x) dA(x)) dx d - dx dB(x) (Hint: A(x). B(x) = A(x)! dx
