Need help please

A uniformly charged solid sphere of charge is placed at the origin. It has a total charge of q = -8.41 nC and a radius of R = 6.37 cm. a. (Q7 ans 2 pts, Q8 work 4 pts) What is the electric field at a radius of r = 13.6 cm? b. (Q9, 6 pts) What is the flux of electric field through a sphere of radius r that is also centered at the origin? c. (Q10, 6 pts) What is the flux of electric field through a sphere of radius R/2 that is also centered at the origin? d. (Q11, 6 pts) What is the electric field at a radius of R/2? To continue, please give the magnitude of electric field at a radius of r (part a) in units of kN/C. Your partial credit work should give the direction of this field
