sorry !!
the image is small

im gettin TP as 2pi√8l/9g

Mine is totally diff[2]..............maybe some calculation mistake

but steps would be..find COM,then find MOI abou axis(after shifting)
and then apply time period formula for physical pendullum
t=2pi√(I/mgd)

hope u will ssolve now....[1]

a friendly advice..... dont use redymade formulaes derive it frm start.....

isn't it supposed to be 3l/4 instead of 3l/2

ohh..yes calc. mistake.........so now i think ull get a Machin ANSWER..HAV EDITED IT!!!!! LUK ABOVE!!!!

but answer given is A and D.

OHH!!! MY MISTAKE ALONG YY/ THE MI WILL BE DIFFERENT SO.. YES ITS AD ONLY!!!!!

I have a doubt,
for a rod MI is mlsquare/12 ,this is about an axis perpendicular to the plane containing the rod or along the plane.????

IT SHUD BE AD ONLY!!!!!!!!!

for rod attached below....xx/ is along and yy/ is perpendicular!!!!!!!
