Question 80 of 90

AB and CD are smooth parallel rails, separated by a distance l, and inclined to the horizontal at an angle θ . A uniform magnetic field of magnitude B, directed vertically downwards, exists in the region. EF is a conductor of mass m, carrying a current i. For EF to be in equilibrium,


1 .         I   m u s t   f l o w   f o r m   E   t o   F 2 .         B i l   =   m g   tan   θ 3 .         B i l   =   m g   sin   θ 4 .         N o n e   o f   t h e s e . p l e a s e   a n s w e r   i t   c o r r e c t l y

Bilcos(theta)=mgsin(theta) Bil=mgtan(theta) Thanks
