(8%) Problem 12. A hollow, uniformly charged sphere has an inner radius ofri sphere has a net charge of Q = 2.5 C. 0.11 m and an outer radius of r229 m. The what is the magnitude of the electric field n newtons per coulomb, at a distance of r-0.19 m from the center of the sphere Grade Deduct Potenti Late W E(r) = sino cotanO asinacoso atan acotan sinh0 cosh tanh cotanho) 4 5 6 Late Poteat Sabmi Attemp .

Explanation / Answer

From Gauss Law ,electric field is given by

E=KQ/R2

E=(9*109)(2.5*10-6)/0.192

E=6.23*105 N/C
