I mass m and side r 26 ABC is an equilateral triangular frame It is at rest under the action of horizontal magnetic field B as shown and the gravitational field 0 B T B r 3 3 1 The frame remains at rest if the current in the frame is 2mg rB 2 The frame remains at rest if the current in the frame is 2mg rB 3 71 2 3 The frame is in simple harmonic motion when frame is slightly displaced in its plane perpendicular to AB The r 3 period of oscillation is g 4 For same as in above option the period of oscillation is 71 2 3r 2g
