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)?
