A sphere of radius $4.0\mathrm{cm}$ has a charge of $23\mathrm{nC}$ evenly distributed throughout the sphere. What is the electric field strength $1.0\mathrm{cm}$ from the center of the sphere?

Understand that the problem involves finding the electric field inside a uniformly charged sphere. For points inside a uniformly charged sphere, the electric field is given by the formula: $E=\frac{kQr}{R^3}$, where $k$ is Coulomb's constant, $Q$ is the total charge, $r$ is the distance from the center, and $R$ is the radius of the sphere.
