A hollow conducting sphere with inner radius a=1.0m and outer radius b=2.0m is shown in figure (Figure 1). Say a charge q=7.0nC is placed at the center of the sphere denoted by O. Here m denotes meter and 1nC denotes one nano coulomb or 1×10−9C. coulomb constant is k=8.987×109N⋅m2/C2. and r is the distance from the center. (a) Potential at r=(a+b)/2 is, V=?volt Potential Give your answer up to at least three significance digits. (b) Electric Field at r=(a+b)/2 is E(r)=?N/C Electric field Give your answer up to at least three significance digits (c) Magnitude of the electric Field at r=a/2 is E(r)=?N/C Electric field Give your answer up to at least three significance digits.
