Question

4. Two charges are located along a line as in the sketch. Charge A has a positive charge of +Q Coulombs, Charge B has a positive charge of +2Q coulombs. At which of the points labeled 1, 2, 3, or 4 could a test charge remain at rest? -Gi-3-04 B) 2. C) 3 D) 4. E) The answer depends on the test charge, which is not given. 5. A negative-2.0 C charge is placed at the origin (lower right in the sketch). An id distance on the y axis. Find the magnitude and direction (relative to the positive x-axis) of the net force on the charge at the enti al d arge is placed a a - 0.2 m to the left of the origin on the x axis. A positive +2.0 uC charge is placed 0.3 m from the origin origin. +2 HC A) 2.0 N, 45° B) 1.3 N, -45° C) 0.6 N, 45° D) 0.6 N, 225° E) 1.3 N, 135 2 HC 2 HC

Explanation / Answer

4.(B) 2

Because both charge are positive , so net electric feild is zero somewhere in between them. Now, since A has lower magnitude than B so, the equilibrium point must be closer to A.
