Question

7 8 wote done can also be deternined by considering mavement across equipotemtials. This cas be Vn is the electrix potential af poist P This tells us thst the work done by you is dependent only on the magnitude and type(+or- of the electric charge you are trying to move, and the difference in electric potential from the ending poim ro the starting point. Both of these equations could yield positive or negative values for wok Positive work for you means that you (or some outside inftuence) are doing work againss the field to move the charge. Negative work for you means that you aren't doing any work and the particle moves the way the field would naturally push oe pull the charge. Use the equations above that determines work and your sketcbes for electric fields and equipotentials) to state if each of the situations below would be + or- work: 3) a) Moving a + charge from a point of higher eleetric potential to one of lower electric potential. Explain your reasoning for this first case. b) Moving a - charge from a point of higher electric potential to one of lower electric potential. o) Moving a + charge from a point of lower electric potential to one of higher electric potential d) Moving a-charge from a point of lower electric potential to one of higher electric potential.
