See AnswerQ: A charge q1 = +5.00 nC is placed at
A charge q1 = +5.00 nC is placed at the origin of an xy-coordinate system, and a charge q2 = 2.00 nC is placed on the positive x-axis at x = 4.00 cm. (a). If a third charge q3 = +6.00 nC is now place...
See AnswerQ: Two identical spheres with mass m are hung from silk threads of
Two identical spheres with mass m are hung from silk threads of length L (Fig. P21.62). The spheres have the same charge, so q1 = q2 = q. The radius of each sphere is very small compared to the distan...

Consider the electric dipole of Example 21.14. (a). Derive an expression for the magnitude of the electric field produced by the dipole at a point on the x-axis in Fig. 21.33. What is the direction o...
See AnswerQ: A conducting sphere is to be charged by bringing in positive charge
A conducting sphere is to be charged by bringing in positive charge a little at a time until the total charge is Q. The total work required for this process is alleged to be proportional to Q2. Is thi...
See AnswerQ: A -3.00-nC point charge is on the
A -3.00-nC point charge is on the x-axis at x = 1.20 m. A second point charge, Q, is on the x axis at -0.600 m. What must be the sign and magnitude of Q for the resultant electric field at the origin...
See AnswerQ: Is it possible to have an arrangement of two point charges separated
Is it possible to have an arrangement of two point charges separated by a finite distance such that the electric potential energy of the arrangement is the same as if the two charges were infinitely f...
