a.What electric potential difference exists across a 5.2 F capacitor that has a charge of 2.1 10-3 C?
how do i use uF and C into a formula to find answer??

b.An oil drop is negatively charged and weighs 8.5 10-15 N. The drop is suspended in an electric field intensity of 5.3 102 N/C.
(a) What is the charge on the drop?
(b) How many electrons does it carry?

c.The electric field intensity between two large, charged, parallel metal plates is 7500 N/C. The plates are 0.05 m apart. What is the electric potential difference between them?
