A spherically symmetric charge distribution produces the electric field \( \vec{E}=\left(4300 r^{2}\right) \hat{r} \mathrm{~N} / \mathrm{C} \), where \( r \) is in \( \mathrm{m} \). What is the electric field strength at \( r=19.0 \mathrm{~cm} \) ? Express your answer in newtons per coulomb. Part B What is the electric flux through a 38.0-cm-diameter spherical surface that is concentric with the charge distribution? Express your answer in newton meters squared per coulomb. How much charge is inside this \( 38.0 \)-cm-diameter spherical surface? Express your answer in coulombs.
