A set of charged plates have an area of 8.22*10^-4 m 2 and
separation 2.42m1045 m. The
plates are charged with
5.24*10^-8 C. What is the
potential difference V between
the plates?
(Untt = V)

a.metals can become magnetic if they have many spinning electrons that create magnetic fields.d.only some metals are attracted by magnets; these metals are called ferromagnetic.

d.wrapping an insulated wire around a metal with ferromagnetic properties and applying an electric current.

the answer is f1 and d2 because if you put equal force on those two points the beam would balance trust me on this
