In this problem, i and j refer to unit vectors in the X and Y directions respectively. A small particle whose mass is 10-12 kg and carrying a net charge of +5 μC enters a region of space where the magnetic field is 2T i. The velocity of the particle at some instant of time is 0.03C i + 0.04Cj (where C = speed of light).
If the magnetic field were to be directed perpendicular to the particle instead of in the X direction as given, what would be the radius of the particle's resulting circular motion?
a. what rms current is drawn by a 3400-w electric room heater when running on 120 v rms?b. what is the power
The drawing shows two situations in which charges are placed on the x and y axes. They are all located at the same distance of 6.1 cmfrom the origin O. For each of the situations in the drawing, determine the magnitude of the net electric field at..
