What is the radial electric field at the point r=0.5(R1+R2)? Give your answer in units of kN/C. I got -114.46 but it's telling me that's incorrect. Not sure where to go from here. (8.99*109)(-25) / 142 is the equation I think. What did I do wrong? A hollow non-conducting spherical shell has inner radius R1 =9 cm and outer radius R, =19 cm. A chargeQ =-25 nC lies at the center of the shell. The shell carries a spherically symmetric charge density that increaseslinearly with radius,p= Ar forR1
