A point charge Q1 +q is placed at the pointr--a and a point charge Q2-:-4 is placed at the point x +a as shown in the diagram below. A positive test charge go is placed a distance x away along the x axis. Derive a symbolic expression for the magnitude and direction of the electrostatic force on the test charge. (b) Show that when the test charge is very far away (x> a), the force is not zero, but is...
Example: Two positive charges of charge q are a distance 2a apart. A third charge of charge Q is a distance y above the midpoint of the other two Consider the charge configuration shown below. charges. What is the net force on Q? What is the direction of the net force on the +q charge? B y +4 A D+Q E s/2 s/2 y q +0 X-a Claiverity of Colerade, Boslder (28n D
Two point charges, with charge magnitudes q and Q, are placed a distance r apart. In this arrangement, each point charge experiences a force of magnitude F. In the three scenarios, q. Q, and rare changed to some multiple of their original values. In each case, fill in the missing value on one of the variables that will result in a force between the point charges that is equal in magnitude to the original F. Original Answer Bank Scenario 1...

Explain why your answer does not depend on the sign or the magnitude of q 3Q (b) For the two charges shown, determine where a third charge q should be placed so that it experiences no net force 3Q
5. Two particles carrying a charge of q-+8q and qp -2q are fixed in place the origin while the charge qz is at a distance i can a proton be placed so that it is in equilibrium (the net force on equilibrium stable or unstable? (That is, if the proton is displaced, do the forces d back to the point of equilibrium or drive it further away? R. A what po int (other than infinitely away) t is zero)? Is...
(a) Given two point charges, Q and 2Q, a distance d apart, is there a point along the straight line that passes through them where E = 0 when their signs are opposite? If yes, state roughly where this point will be. (b) Given two point charges, Q and 2Q, a distance d apart, is there a point along the straight line that passes through them where E = 0 when their signs are the same? If yes, state roughly...
Charges of -q and +2q are fixed in place, with a distance of 2 m between them. A dashed line is drawn through the negative charge, perpendicular to the line between the charges. On the dashed line, at a distance L from the negative charge, there is at least one spot where the total potential is zero. Find L.
