Question

A long cylindrical rod with length 8 m and radius 4.1 cm is uniformly charged with total charge 7.8 μC.  Then, a hole is carved out of the center of the rod in the shape of a sphere of radius 1.8 cm.  What is the electric field at a distance 6.3 cm away perpendicular from the center of the object?

 

Give your answer in units of NμCNμC (or 1×106NC1×106NC).

Hint: What would you "add" to a solid object to model a hole?
