a) Zero. No field in a charged sphere.
b) Still zero
c) Now you can use your field equation. The field is a vector so you can sum the influence of the point charge and shell. Note r is different for each.
d)Again, none
e) all of it
A 4.70 nC point charge is placed at the centre of a hollow metal sphere that has an inner radius 4.70 cm and an outer radius 17.6 cm. The metal sphere itself is charged to 8.40 nC.
a)What is the magnitude of the electric field at a distance of 1.60 cm from the centre?
b)What is the magnitude of the electric field at a distance of 11.2 cm from the centre?
c)What is the magnitude of the electric field at a distance 29.7 cm from the centre?
d)How much charge is on the inside surface of the hollow sphere?
e)How much charge is on the outside surface of the hollow sphere?
NOTE: Please i'm not asking for the final answer... Just a guideline on how to solve these questions... Thanks in advance for your help!!:-)
