2. Two para llel conducting rails, The U-shaped system is inclined with an to the W15.00 om. by 40° to the horizontal, as suggested in the drawing magnetic field pointing upward with a strength of 600 mT. A 0.050 kg can slide frictionlessly down the rails (staying parallel with the of4.00 x 10-3 . There is a v current is induced in the rod, generating a braking f rod, including direction of current flow) in the rod when the rod achieves its terminal speed, and what is that terminal speed? rod is released and slides down, it begins to accelerate. As the rod slides downward, a g rod of mass force. Determine the current (in the w=15 cm 40

Explanation / Answer

At terminal velocity, Force due to gravity down the incline = magnetic force up the incline

mg sin 40 degree = i*w*B * cos 40 degree

0.050*9.8*tan 40 degree = i*0.15*600e-3

i = 0.050*9.8*tan 40 degree/[0.15*600e-3]

= 4.568 A answer
