Just need help with the second part I cant figure it out A negative point charge – is at the center of a hollow insulating spherical shell, which has an inner radiusR₁ and an outer radius R₂. There is a total charge of +3Q spread uniformly throughout the volume of theinsulating shell, not just on the surface. What is the electric field at postion r away from the center? Use el asthe electric constant.(a) When r is less than R1-Q/(4*pi*e0*r^2)Q4.π.e0.r²(b) When r is between R1 and R2(-Q+(3*Q*r^2/R2^2))/(4 X-Q+ (30²)4.π.e0.²(c) When r is larger than R2Q/(2*pi*e0*r^2)Q2.π.e0.²
