Task 31037.
The voltage is applied to the horizontally and vertically deflecting plates of the oscilloscope: Ux = 20cospt, V; Uy = 10cos (pt f0), V. The sensitivity of the plates is the same and equal to 1 mm / V. Write the equation of the trajectory along which the point from the electron beam moves on the oscilloscope screen, for two cases: a) φ0 = 0; b) φ0 = n / 2.
A detailed solution with a brief record of the conditions, formulas and laws used in the solution, the derivation of the calculation formula and the answer.
If you have questions about the solution, write. I try to help.
