The formula for the electric field of a nonconducting solid sphere is given by E = kQr / r^3, where E is the electric field, k is the Coulomb's constant, Q is the total charge of the sphere, and r is the distance from the center of the sphere to the point where the electric field is being calculated.
The electric field of a nonconducting solid sphere decreases with distance from the center, following an inverse cube law. This means that as the distance increases, the electric field decreases at a faster rate.
The direction of the electric field at any point outside the sphere is radial, meaning it points directly away from or towards the center of the sphere. This direction is determined by the sign of the total charge of the sphere.
No, the electric field inside a nonconducting solid sphere is always zero. This is because the charge on the surface of the sphere creates an equal and opposite electric field that cancels out the electric field inside the sphere.
The electric field of a nonconducting solid sphere follows an inverse cube law, while the electric field of a conducting solid sphere is constant throughout the space inside the sphere. This means that the electric field of a nonconducting solid sphere decreases faster with distance from the center compared to a conducting solid sphere.
