Consider a uniform electric field E of magnitude E = 7.2 N/C. The line segment connecting points A and B in the field is perpendicular to the direction of the field, while the line segment connecting points C and B is parallel to the field. The line segments have equal lengths of d = 0.38 m. Find the potential difference, in volts, between point A and point B.
Enter an expression for the potential difference between point C and point B in terms of E and d.
Calculate the potential difference, in volts, between point C and point B.

a. Va-Vb= 0 volts

The two are perpendicular and therefore would have a difference of zero

b. Vc-Vb= -Ed

We already know V=Ed and in this case d is negative

c. -2.736 volts

(-7.2)*(.38)= -2.736

Plug in what was given for E and d into the equation for b

d. air pressure decreases as altitude increases.
