Question

A -3.0-nC charge is at (0, 0) and a +7.0-nC charge is at (0, 3.0 m). If the potential is taken to be zero at infinity, what is the work required to bring a 1.0-nC charge from infinity to point (4.0 m,0)?

Answer #1

A -3.0 nC charge is on the x-axis at x = -7.0
cm and a +4.0 nCcharge is on the x-axis at x = 20
cm . At what point or points on the y-axis is the electric
potential zero?

Q4. Charge q1 = 2.0 nC is located at (0, 0) and
charge q2 = -4.0 nC is located at (-3.0 cm, 0).
Sketch a diagram of the charge distribution.
What is the electric potential at point A (2.0 cm,0)?
What is the electric potential at point B (3.0 cm, 0)?
What is the change of electric potential from A to B?
How much work is needed to move a third charge q3 =
2.0 nC from A to B?

Charge q1 = 5.5 nC is located at the
coordinate system origin, while charge q2 =
-4.61 nC is located at (a, 0), where a = 0.55 m.
The point P has coordinates (a, b), where
b = 0.25 m. A third charge q3 = 19 nC
will be placed later.
a) Find the electric potential VP at point
P, in volts. Assume the potential is zero at infinity.
b) How much work W, in joules, would you have to...

A 30 nC point charge is positioned at the origin and a -20 nC
point charge is positioned on the x-axis at 1.0 m. Take the
electric potential to be zero at infinity. To three significant
figures, determine: a) the electric potential on the x-axis at 0.5
m. (1 pt) b) the electric potential on the x-axis at 1.5 m. (1 pt)
c) the electric potential energy stored between the charges. (1
pt)
