A charge of a certain polarity has a value of 9nC and is surrounded by a sphere with a radius of 15 centimeters (15 cm) centered on the charge generating an electric field leaving the sphere and in the same direction as the normal of the sphere (see Figure).

a) What kind (positive or negative) is the electric charge in the center of the sphere and explain its answer?

b) What is the electric field (magnitude and sign) at any point on the edge of the sphere due to such charge?

c) What is the electric flow (magnitude and sign) through the sphere due to this charge? d) Determine the electric flux (magnitude and sign) using Gauss's Law directly
