Q1. Answer the follow :

A) As a charged object moves opposite the direction of the electric field in a region of space, the electric potential is

B) A positively-charged object is near a positively-charged source. As the object moves away from the source

C) Elmer has found that the electric potential at one location is 2.5 V and the electric potential at a nearby location is 1.0 V. The locations are 1.5 cm apart. What is the magnitude of the electric field between these two locations? Express your answer in units of volts per meter, V/m.

D) Elmer tells you that he has measured an electric field to be 3.0 V/m between two locations on the board. The regions are 2.5 cm apart. What is the magnitude of the electric potential difference between the two locations? Express your answer in units of volts, V.

Explanation / Answer

1. As electron moves towards positive charge(opposite to electric field) means it is going to the lower potential, hence

Option (c) is correct.

------

2.

Positive charge moves in the direction of electric field towards negative charge(higher potential)

Hemce option (a) is correct.

-------

3.

Electric field

E= V/d

= (2.5-1)/0.015

= 100 V/m

----

V= Ed= 3*2.5*10^-2

= 0.075 V
