Two long, straight wires cross each other at right angles, as shown in the figure below

Two long, straight wires cross each other at right angles, as shown in the figure below. (a) Find the direction and magnitude of the magnetic field at point P, which is in the same plane as the two wires. (b) Find the magnetic field at a point 30.0 cm above the point of intersection (30.0 cm out of the page, toward you).

A uniform, upward electric field E of magnitude 2.00 x 10^3 N/C has been set up between two horizontal plates by charging the lower plate positively and the upper plate negatively. The plates have length L = 10.0 cm and separation d = 2 cm. An electron is then shot between the plates from the left edge of the lower plate. The initial velocity v0 of the electron makes an angle theta = 45 with the lower plate and has a magnitude of 6 x 10^6 m/s. a) Will the electron strike one of the plates? b) If so, which plate and how far horizontally from the left edge will the electron strike?



Could u make a video on this my professor isn’t the best, and I’m really struggling your help would be appreciated.
