Physics

The figure below is a section of a conducting rod of radiusR1=1.30mm and length L=11.00minside a thick-walled coaxial conducting cylindrical shell ofradius R2=10.0R1Â Â and the (same) lengthL. The net charge on the rod isQ1=-4.30âˆ—10âˆ’12Cthat on the shell is Q2=-4.00Q1.
a) What is the magnitude E of the electric field at a radialdistance of r = 2.50R2?
b) What is the direction of the electric field at the radialdistance (inward, outward, or zero)? Give reasons!
c) What is the magnitude E of the electric field at a radialdistance of r = 3.60R1?
d) What is the direction of the electric field at that radialdistance (inward, outward, or zero)? Give reasons
