A total charge of \( -6.50 \mu \mathrm{C} \) is uniformly distributed within a sphere that has a radius of \( 0.150 \mathrm{~m} \). What is the magnitude and direction of the electric field at \( 0.300 \mathrm{~m} \) from the surface of the sphere?
(A) \( 2.89 \times 10^{5} \mathrm{~N} / \mathrm{C} \), radially inward
(B) \( 9.38 \times 10^{5} \mathrm{~N} / \mathrm{C} \), radially outward
(C) \( 6.49 \times 10^{5} \mathrm{~N} / \mathrm{C} \), radially outward
(D) \( 1.30 \times 10^{6} \mathrm{~N} / \mathrm{C} \), radially inward
