A1.60 m tall person lifts a 2.10-kg book from the ground so it is 2.20 m above the ground. what is the potential energy of the book relative to (a) the ground and (b) the top of the person’s head? how is the work done by the person related to the answers in parts (a) and (b)?

Apositive charge moves in the direction of an electric field. which of the following statements are true? check all that apply. check all that apply. 1.the potential energy associated with the charge decreases. 2. the electric field does positive work on the charge. 3. the electric field does negative work on the charge. 4. the potential energy associated with the charge increases. 5. the electric field does not do any work on the charge. 6. the amount of work done on the charge cannot be determined without additional information.
