28. ••• Two large parallel plates are separated by 3.0 cm and connected to a 12-V battery. Starting at the negative plate and moving 1.0 cm toward the positive plate at a 45° angle (▼ Figure 16.30),

(a) what value of potential would be reached, assuming the negative plate were defined as zero potential?

(b) Repeat part (a)

except move 1.0 cm directly toward the positive plate.

Explain why your answers to

(a) and

(b) are different.

(c) After the movement in (b), suppose you moved 0.50 cm parallel to the plane of the plates. What would be the electric potential value then?
