An electric field line is point from the left towards the right. Where will an electron move when placed in the field?

Consider the given diagram of two electrical charges. Which of the following is true about charges A and B?

A point charge of charge is placed in a uniform electric field of strength going to the right. The charge is then moved at an angle of below the horizontal to the right. What is the net work done on this charge?

A student has a neutrally charged glass rod and a neutrally charged silk cloth. When the student rubs the silk cloth on the glass rod, the rod acquires a net positive charge. What is the charge on the silk cloth after the student performs this experiment?

If the test charge is increased by a factor of 4, what happens to the electric potential of that charge?

By how much will the electric field change if the charges of all source charges are increased by a factor of , and the test charge is increased by a factor of ?

Two charges of and are placed away from each other. Another charge is placed in between these two charges. Where should this third charge be placed in order for it to feel no net electrostatic force?

A point charge of coulombs experiences a force of in an electric field. What is the magnitude of this electric field?

Two identical conducting spheres are attached to insulated posts and charged so that and .

The spheres are brought together so they touch, then moved back apart. What is the charge on now?

Determine the total electric charge of molecules in solution in Coulombs.
