They attract each other before touching and repel each other after touching. % Draw in a few equipotential lines in Fig. x[iGV0Dp{B8f#B!l>^wzEu?U]{U=t|][qW{OZwUOoxgS:#G-4kF=WM+;S8sQ3Q*sy 5eqNK\"}+\(NV]gVH2 :g$DB!JXQB The 80-kg ventilation door OD with mass center at G is held in the open position shown by means of a moment M applied at A to the opening linkage. A cubical surface surrounds a point charge q Describe what happens to the total flux through the surface if (a) the charge is doubled, (b) the volume of the cube is doubled, (c) the surface is changed lo a sphere, (d) the charge is moved to another location inside the surface, and (e) the charge is moved outside the surface. . Sphere B has an initial, Q:-6.25 nC stream If the distance is decreased to a distance of 0.40d, what is the strength of the resulting force? A heater has a resistance of 10.0 . magnitude of the total force on charge 3 is most nearly Report F2 in terms of the given quantities in the 21.09 Two identical conducting spheres, fixed in place, attract each other with an electrostatic force of 0.108 N when their center-to-center separation is 50.0 cm. (C) 4.0 F and 3 is 6.0 N; the force between charges 2 and 3 is 5.0 N; and the force between charges 3 and 4 is 3.0 N. The Compute, Q:An electric dipole consists of two equal but unlike charges separated As a result, the electrostatic force between A and B, initially F, becomes (1) 3F/8 (2) F (3) F/2 Two identical conducting spheres carry charges of +5.0 C and -1.0 C, respectively.
