Homework Statement A rotating coil is a common device for measuring magnetic fields. Consider a coil of area A and N turns that is rotated at angular frequency w in a magnetic field. The position of the coil is adjusted so as to produce a maximum induced current Imax which can be measured by...

thanks for your help. I really appreciate it. ^_^

so.. I can just assume that? wow.. that seems too simple..

I've already presented all the information given for that problem. Although.. sorry about the typos..

T1 is the vertical force pulling m1 up and T2 is the horizontal force pulling m2 towards the pulley. And it seems that T2 is the only force that acts on m2..

ok here's an image to show what's going on here http://www.geocities.com/liquid_fuse/masses.gif The mass is a frictionless surface so what other forces could be acting on it on the x-axis?

Two masses are connecte by a ligh string over a light, frictionless pulley the table surface that m2 is on is also frictionless. Apply the work-energy theorem for this system to calculate the speed of the masses after the masses have moved a distance delta x starting from rest. Note that the...
