A plastic circular loop of radius R and a positive charge q is distributed uniformly around the circumference of the loop. The loop is then rotated around its central axis, perpendicular to the plane of the loop, with angular speed omega.
If the loop is in a region where there is a uniform magnetic field B directed parallel to the plane of the loop, calculate the magnitude of the magnetic torque on the loop.
well, i did this
F=qvB
and know that v = w(omega).R
it gives me F=qwRB
and Torque = F. L, then i got T=qwR^2B
my answer seems not correct.., please advise.
