1. An electron moves in a circular path in the magnetic field of an electromagnet. The plune of the electron's Sicular path is parallel to the smooth vole faces of the electromagnet. In the region where the electron is moving the magnetic field is uniform and has magnitude 0,50 T. The electron moves with a speed of 1.5 x 10 m/s. a. If someone could observe the electron from the north pole of the electromagnet, would the electron inove clockwise...

An object moves in a circular path at a constant speed. What is the relationship between the directions of the object's velocity and acceleration vectors? The velocity and acceleration vectors point in opposite directions. The velocity and acceleration vectors are perpendicular. The velocity vector points in a direction tangent to the circular path. The acceleration is zero. The velocity vector points toward the center of the circular path. The acceleration is zero. The velocity and acceleration vectors point in the...
