Two thin rectangular conductors are placed very close to each other so their surfaces are parallel. The first conductor has a total excess charge of 3.75 C.

a. What is the charge of the other plate, in C, if it is grounded?

b. The plates are rectangles with side lengths 2.8 cm and 4.1 cm. What is the charge density on the second plate in C/m²?

c. What magnitude of force (in N) would a single electron experience in the region between the plates?
