Figure 1-69 Info on each layer Practical values and theoretical values match. This means our model is correct. 1.5 Hollow sphere 1 Now, if we are given a problem that involves a point charge, how do we solve it? A point charge is a particle which is zero-dimensional, does not take up space. A point particle is an appropriate representation of any object whose size, shape, and structure is irrelevant in a given context. 6 How do we represent such a particle using this program? Let’s try it by two different methods. A positive point charge Q is centered in a metal hollow sphere. Inner radius R1, Outer radius R2. The Sphere is connected with ground, the potential of the sphere is zero. Here we will draw a plot of the field profile E=(r) First of all, I should notice you that this method is not correct. 1.5.1 Create a new file. R1 “File”→“New”→ “Electrostatics Problem” 6 H.C.
