Please help. Thanks.

1. Volt meter measures the potential between two large parallel plates to be 60 volts. The plates are 3cm apart. Find the magnitude of the electric field between them.
2. What work is done when 5C is raised potential by 12.45 volts?

* I really don't have any idea how to answer this please help. I need it asap cuz I have a test about this tomorrow at 7 am. And its now 8pm here in Philippines. :)

E=V/d = 60/.03 = 2000 v/m

W = qV = 5*12.45 = 62.25 J
