An insulating sphere with a radius of (3.3E-2) m has a uniform charge density of (6.74E-6) C/m^3 throughout its volume.
(1)Find the magnitude of the electric field at a point (5.7E-2) m from the center of the sphere.
(2) Find the magnitude of the electric field at the surface of the sphere
(3) find the magnitude of the electric field at a point (2E-2) m from the center of the sphere.
Thanks!
Relevant Equations:
Volume of sphere:4/3(pi)r^3
(D) Charge Density=Charge/volume
[Attempt]
I tried to find Q (charge) using D=Q/(4/3(pi)r^3)
Now I am Lost. There are many Electrical Field Equations. I tried plugging into EA=Q/ε but it did not work. I also tried E=q/((4/3(pi)r^2)r^3)
Please help me solve this. Can I see a step by step guide?
Thank you
