In the diagram, q1 = +3.25*10^-9 C. What is the potential difference when
you go from point B to point A?
q1
A
B
0.150 m
0.250 m

ΔV = 78 V

Explanation:

The potential at a point due to a point charge is given as:

where,

V = Potential at the point

k = Colomb's Constant = 9 x 10⁹ Nm²/C²

q = charge = 3.25 x 10⁻⁹ C

r = distance

AT POINT A:

AT POINT B:

Now, the potential difference will be:

ΔV = 78 V

the earths atmosphere is made up of nitrogen and oxygen. solids can turn into gasses through a process called sublimation. sublimation is the transition of a substance directly from the solid to the gas phase, without passing through the intermediate liquid phase.
