The two conducting rails in the drawing are tilted upwards so they make an angle

Question

The two conducting rails in the drawing are tilted upwards so they make an angle of 30.0 with respect to the ground. The vertical magnetic field has a magnitude of 0.050 T. The 0.18 kg aluminum rod (length = 1.6 m) slides without friction down the rails at a constant velocity. How much current flows through the bar?
A

The two conducting rails in the drawing are tilted upwards so they make an angle of 30.0 with respect to the ground. The vertical magnetic field has a magnitude of 0.050 T. The 0.18 kg aluminum rod (length = 1.6 m) slides without friction down the rails at a constant velocity. How much current flows through the bar?

Explanation / Answer

Here ,

Fm , magnetic force = BIL

Fg = mg

Now , for moving with contant velocity

Fg*sin(theta) = Fm * cos(theta)

0.050 * 1.6 * I * cos(30) = 0.18 *9.8 * sin(30)

solving for I

I = 12.73 A

current flows through the bar is 12.73 A
