Which object had more potential energy when it was lifted to a distance of 10 meters? show your
calculation. (remember that gravity = 9.8 m/sec2)

An observer that stands still as the electron moves by him, will observe

The electric potential v is constant everywhere within a certain region of space. which statement below is true? the choices are: the electric field is also constant (but not zero) within the region. a charged particle placed within the region will experience an electric force. the electric field is zero everywhere within the region. the electric field varies from place to place within the region.

The electric field direction is defined by the direction of the force felt by (select one of the following answers): 1. a negative charge. 2. a positive charge. 3. both positive and negative charges.
