Question

A charge moves with an initial speed of 1.0 cm/s upwards along the y-axis. The charge moves through a magnetic field of magnitude 1.0 microTesla pointing downward along the y-axis. If the charge is initially located at the origin of the x-y-plane, what is the charge's final position after 4.0 seconds have passed (enter the x coordinate in the first textbox, enter the y coordinate in the second textbox)? Suppose that the magnetic field pointed right along the x-axis? would this alter your answer (enter "yes" or "no" in the third textbox)?

Explanation / Answer

the magnetic force on moving charge is: F=qv x B, therefore if v vector and B vector are parallel like in our case, their cross product will provide zero force. therefore charge will be at point of 4 cm on y axis after 4 seconds. If force will be along x axis, the force will be to the positive z direction and charge will start moving in circle trajectory.
