15. A charge 5q is a distance 2d from P, a charge 5q is a distance d from P, and two charges +5q are each a distance d from P, so the electric potential at P isq (8.99 109 N m 2 C2 )(5.00 1015 C) 1 1 1 1 V= + = = 4 0 2d d d d 8 0 d 2(4.00 102 m) q= 5.62
Hudson VCC - PHYS - 219
17. First, we observe that V (x) cannot be equal to zero for x &gt; d. In fact V (x) is always negative for x &gt; d. Now we consider the two remaining regions on the x axis: x &lt; 0 and 0 &lt; x &lt; d. (a) For 0 &lt; x &lt; d we have d1 = x and d2 = d x. LetV ( x) = kFG
Duquesne - PHYS - 264
16. Since according to the problem statement there is a point in between the two charges on the x axis where the net electric field is zero, the fields at that point due to q1 and q2 must be directed opposite to each other. This means that q1 and q2 must
East MS CC - PHYS - 361
18. In applying Eq. 24-27, we are assuming V 0 as r . All corner particles are equidistant from the center, and since their total charge is 2q1 3q1+ 2 q1 q1 = 0, then their contribution to Eq. 24-27 vanishes. The net potential is due, then, to the two +4q
Cogswell Poly - PHY - 287
19. (a) The electric potential V at the surface of the drop, the charge q on the drop, and the radius R of the drop are related by V = q/40R. Thus8.99 10 9 N m 2 / C 2 30 10 12 C q R= = = 5.4 10 4 m. 4 0V 500 V (b) After the drops combine the total volum
Mississippi Gulf Coast Community College - PHY - 262
20. When the charge q2 is infinitely far away, the potential at the origin is due only to the charge q1 : q1 = 5.76 107 V. V1 = 4 0 d Thus, q1/d = 6.41 1017 C/m. Next, we note that when q2 is located at x = 0.080 m, the net potential vanishes (V1 + V2 = 0
Caldwell College - PHYS - 232
21. We use Eq. 24-20: V=9 2 2 30 p ( 8.99 10 N m C ) (1.47 3.34 10 C m ) = = 1.63 105 V. 2 2 9 4 0 r ( 52.0 10 m )1

American Dubai - PHYS - 122
25. (a) From Eq. 24-35, we find the potential to be V =2 L / 2 + ( L2 / 4) + d 2 ln 4 0 d (0.06 m / 2) + (0.06 m) 2 / 4 + (0.08 m) 2 = 2(8.99 109 N m 2 C2 )(3.68 1012 C/m) ln 0.08 m = 2.43102 V. (b) The potential at P is V = 0 due to superposition.
The Petroleum Institute - PHYS - 241
26. Using Gauss law, q = = +495.8 nC. Consequently, q (8.99 109 N m 2 C2 )(4.958 107 C) V= = = 3.71104 V. 4 0 r 0.120 m

28. The dipole potential is given by Eq. 24-30 (with = 90 in this case) V= p cos p cos 90 = =0 4 0 r 2 4 0 r 2since cos(90) = 0 . The potential due to the short arc is q1 / 4 0 r1 and that caused by the long arc is q2 / 4 0 r2 . Since q1 = +2 C, r1 = 4.0
Andrew Jackson - PHY - 253
27. Since the charge distribution on the arc is equidistant from the point where V is evaluated, its contribution is identical to that of a point charge at that distance. We assume V 0 as r and apply Eq. 24-27:V= 1 +Q1 1 +4Q1 1 2Q1 1 Q1 + + = 4 0 R 4 2 R
Claflin - PHYS - 201
29. The disk is uniformly charged. This means that when the full disk is present each quadrant contributes equally to the electric potential at P, so the potential at P due to a single quadrant is one-fourth the potential due to the entire disk. First fin
