A positive charge is placed in an electric field. It starts at rest but is free to move. What does the test charge do? It stays at rest. It moves towards the nearest negative charge only (if there is one). It moves along electric field lines in the opposite direction the arrows point It feels a force pointing tangent to the field lines and moves according to the force. Three charges, -9, +q, and -2q are...
Below are shown what happens to the total charge in a solid
conductor, fluid with positive and negative ions, and insulator
when a charged rod is brought close by.
Assuming the number of positive and negative charges inside the
conductor, fluid, and insulator is the same, in which case will the
attractive force between the rod and the ball be the largest?
The attractive force is the same in all cases.
Solid insulator
Fluid with ions
Solid conductor
One positive charge and one negative charge, each of magnitude 4x10^-6 C, are located a distance of 0.1 m from each other. a) What’s the magnitude of force exerted on each charge? b) On a drawing, indicate the direction of the forces acting on each charge. c) Draw electric field lines between two charges.
