Field inside a charged sphere

[Titan97]

What is the direction of field inside a charged non-conducting sphere?
Using gauss law, I can find the magnitude of electric field inside the shell by assuming a spherical Gaussian surface. But how can I find its direction?

Also, if electric field exists inside a charged sphere, wouldn't the charges start moving?

What's the charge distribution? If the distribution is spherically symmetric, you know the direction of the field must be radial.

Also, if electric field exists inside a charged sphere, wouldn't the charges start moving?

Not if it's a non-conductor.
