Please help me with this question
Q.14. Rods AB, BC, CD & DA for a square loop having current i, mass and length of each rod is m and l respectivety, issituated in a uniform magnetic field B as shown in the figure andit can rotate about axis $P_1{P}_2$, Then, find the angular acceleration of the square loop at t = 0 in $rad/se{c}^2$.
(where B = 10 Tesla, i = 2 amp, m = 5 kg).
