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 upwards, exists in the region. EF is a conductor of mass m, carrying a current i. For EF to be in equilibrium,

Options:(select one or more)

Answer:

A, B

Solution:

Ans (A,B)

From the free body diagram on the incline:
