Question

Two equal and opposite charges are a small distane apart, forming an electic dipole. A positive charge is placed above these charges, as shown in the figure, equidistant from both of them. Which diagram below best gives the direction of the net force the dipole exerts on the charge ? A meta sphere of radius 2.0 cm carries an excess charge o f3.0 muC. What is the electic field 6.0 cm from the center of the sphere? As shown in the figure, the charge Q is midway between two other charges What must be the charge q1 so that charge q2 remains stationary as Q and q1 are held in place? The force of attraction that a -30,0 muC point charge exerts on a + 94.) muC pint charge has magnitude 4.00 N. How far apart are thes two charges? A small glass bead has been charged to 3.2 nC. What is the strength of the electic field 2.0 cm from the center of the bead? Apiece of plastic has a net charge of + 2.00 muC. How many more protons than electons does this piece of plastic have?
