Q. A uniform electric field of magnitude 375 N/C pointing in the positive x-direction acts on an electron, which is initially at rest. After the electron has moved 3.20 cm, what is (a) the work done by the field on hte electron, (b) the change in potential enery associated with the electron, and (c) the velocity of the electron?
Q. The magnitude of vector is 40.3 units and points in the direction 340° counterclockwise from the positive x-axis. Calculate the x-component of this vector.
