What is the electric field
(a)
inside the sphere
(b)
just outside the sphere
(c)

A parallel plate capacitor with air between the plates has a
capacitance of 8 pF (1pF = 10–12 F) What will be the capacitance if
the distance between the plates is reduced by half, and the space
between them is filled with a substance of dielectric constant 6
