IIT JEE Discussion Forum › Mechanics questions › pulley

in d fig shown ABCD is a fixed smooth conducting frame in horizontal plane . T is a bulb of power 100 W. P is a smooth pulley OQ is a conducting rod neglect the self inductince of the loop and resis of any part other than bulb the mass M is mooving down with const velosity 10 m/s bulb lights at its rated power due to induced emf in the loop due to earth magnetic field . find M
