Answer #1

A point charge q1=+2.40μC is held stationary
at the origin. A second point charge q2=−4.30μC
moves from the point x=0.160m , y=0, to the point
x=0.245m, y= 0.245m , y=0.245m
What is the change in potential energy of the pair of
charges?
Express your answer in joules to three significant
figures.
How much work is done by the electric force on q2?
Express your answer in joules to three significant figures.

A point charge with a charge q1 = 2.90 μC is held stationary at
the origin. A second point charge with a charge q2 = -4.10 μC moves
from the point x= 0.170 m , y=0 to the point x= 0.250 m , y= 0.260
m .

A point charge with a charge q1 = 2.20 ?C is held stationary at
the origin. A second point charge with a charge q2 = -4.90 ?C moves
from the point x= 0.110 m , y= 0 to the point x= 0.250 m , y= 0.250
m . ow much work is done by the electric force on q2?

A point charge q1 is held stationary at the origin. A second
charge q2 is placed at point a, and the electric potential energy
of the pair of charges is +5.7 * 10-8 J. When the second charge is
moved to point b, the electric force on the charge does -1.6 * 10-8
J of work. What is the electric potential energy of the pair of
charges when the second charge is at point b?

A positive point charge q1 = 3.0 μC is located at x = 0, y =
