AP Physics 2 10.4 and 10.5 Review

As a proton moves in the direction of the electric field lines...

• it is moving from low potential to high potential and gaining electric potential energy.

• it is moving from low potential to high potential and losing electric potential energy.

• it is moving from high potential to low potential and gaining electric potential energy.

• it is moving from high potential to low potential and losing electric potential energy.

The direction of electric field lines shows the

• direction of the force on a test positive charge.

• size of the field.

• strength of the field.

• all of the above

Two charged spheres of radii 10 cm and 15 cm are connected by a thin wire. No current will flow, if they have

• The same charge on each

• The same energy

• The same potential

• The same field on their surfaces

If a unit positive charge is taken from one point to another over an equipotential surface, then

• Work is done on the charge

• Work is done by the charge

• Work done is constant

• No work is done
