As shown in the figure below, when a charged particle enters a region of magnetic field traveling in a direction perpendicular to the field, it will travel in a circular path. If the magnitude of the magnetic field is 0.180 T, the speed of the particle is 12.0 ✕ 106 m/s, the radius of the trajectory of the path is 106.0 cm, and the charge has a magnitude of 3.20 10-19 C, determine the following.

Consider a region where a 1.85-volt-per-meter electric field and a 2.49-tesla magnetic field exist and are along the same direction. If an 4.72-coulomb charge is in said region, is moving at a direction 32.75 degrees counter-clockwise from the direction of the magnetic field, and is experiencing a total force of 37.88 newtons, determine the speed of the electron, in meters per second. Assume the velocity vector, the electric field, and the magnetic field are all coplanar.
A conductor carrying a current in a magnetic field experiences a force given by the Lorentz equation. It might be written q v * B where the velocity and the magnetic fields are vectors and their product is a vector cross product. In terms of current the charge is carried through a distance L in time t, and the current is the charge per time so the force is I L * B where again the vector cross product comes in and the current is I. How must the wire be oriented in the magnetic field so that it does not experience a force at all? There is no direction in which the force is zero. The wire has to be parallel to the field with the current going opposite to the field. The wire has to be parallel to the field with the current going in either direction in the wire. The wire has to be perpendicular to the field
