Radio Waves Download and run the PhET Radio Waves and EM Field simulation. Use the simulation to answer the following questions. Select the following simulation settings: manual, full field, electric field, and static field. Record your observations. Move the electron down the antenna. Record your observations. Move the electron back to its starting position. Change […]
Write MATLAB® code, which simulates numerically the motion of a single electron emitted from the cathode and plot its trajectory between the electrodes. Use given in (a) values for constants 𝑉𝑎, 𝑉𝑐, 𝑐 and 𝑎.
Question 1: Electric field of a dipole Total: 25 marks Two electric charges 𝑞1 and 𝑞2 of the opposite polarity are positioned along 𝑥–axis at 𝑥1 and 𝑥2 respectively. a) Find analytically1 the location(s) (𝑥0,𝑦0) where the electric field 𝐄 due to these charges is exactly zero2. Provide a line plot of 𝐄(𝑥) which shows […]
What is the potential difference between points A and B and the potential difference between points B and C?
A) In Figure 1 we see a point charge of + 2.00n C. Two circles are drawn around the point charge. The charge is located in the center of these dotted circles. The innermost has a radius equal to 1.00cm, and the outer has a radius equal to 2.00cm. On the innermost circle there are […]
