Question

An air-gap capacitor has the dimensions shown.  It is hooked to a 9 V battery.  The electric field between the plates is 3214.3 N/C. The charge stored on the capacitor = 5.21 x 10-11C.

For each, think carefully if the potential difference is positive or negative!!)

a) How much work would it take to move a -7.5 mC from the top of the left plate (A) to the top of the right plate (B)? [magnitude is 0.0675, be clear if its + or -]

b) How much work would it take to move a -7.5 mC from the top of the left plate (A) to the bottom of the right plate (C)?

c) How much work would it take to move a -7.5 mC from the top of the right plate (B) to the bottom of the right plate (C)?

d) How much work would it take to move a proton from the top of the left plate (A) to the bottom of the right plate (C)?
