assume it to be hanged at point A which is at distance "x" from the center. MI about this point A will be = (mr^2)/2 + mx^2 (say this is denote by MI)

whn displaced a small angle , the restoring torque = mgx sin

thus MI d2 / d2t = mgx sin = mgx   (as sin=)

d2 / d2t = (mgx / (mr^2)/2 + mx^2 )

d2 / d2t =  P  whr P = (mgx / (mr^2)/2 + mx^2 )

Time period T = 2 pi root (1/P)

for T min P shud be max now u can use maxima minima
