1. Estimate or measure the height (in m) above ground level of some location in your environment. It can be the top of your head, the top of your desk, the height of a doorknob, etc. Calculate and state the gravoltage (in J/kg) associated with the Jocation you have chnsen

The statement “if the electric field does positive work on a charge, the potential energy of the system decreases” is true if     The charge is either positive or negative     The charge is negative     The charge is positive     No answer (the statement is false)

(Mulitple choice) If we move a negatively charged particle through an electric field, in which situation is there no change in the electric potential energy of the particle? (explain why that answer is correct) a. We move the particle in the direction of the electric field b. We move the particle in the direction opposite that of the electric field c. We move the particle perpendicularly to the direction of the electric field
