A square current carrying loop made of thin wire and having a mass `m=10g` can rotate without friction with respect to the vertical axis `OO_(1)` passing throught the centre of the loop at right angles to two opposite sides of the loop. The loop is placed in a homogeneous magnetic field with and induction `B =10^(-1)T` directed at right angles to the plane of the drawing `A` current `I=2A` is flowing in the loop Find the period of small oscillations that the loop performs about its position of stable equilibrium

Answer

A, B
