Question: An ideal parallel-plate capacitor has a uniform electric field between the plates, zero field outside. By superposition, half the field strength is due to one

An ideal parallel-plate capacitor has a uniform electric field between the plates, zero field outside. By superposition, half the field strength is due to one plate and half due to the other.
a. The plates of a parallel-plate capacitor are oppositely charged and attract each other. Find an expression in terms of C, ΔV_C, and the plate separation d for the force one plate exerts on the other.
b. What is the attractive force on each plate of a 100 pF capacitor with a 1.0 mm plate spacing when charged to 1000 V?
