To solve the problem, we will use Gauss's Law, which relates the electric field to the charge enclosed by a surface. Here's the step-by-step solution: ### Step 1: Understand the Electric Field The electric field \( E \) is given as: \[ E = 250r \quad \text{(in volts per meter)} \] This indicates that the electric field varies linearly with the distance \( r \) from the origin. ...
