Only a small portion of the rule, the part before zero, would be inserted, as i am co-inciding the zero mark with the water level.
THERE IS NO WAY TO FIND ACCURATE VALUE OF L.
And even if the water level rised a bit, the rod would rise too, won't it? And the value of L would remain same?

What did you write?
This is what I wrote:
"Measure the total length of the rod before immersing it in Water. Use a calibrated tall beaker insttead. Measure the length of the rod inside the tall beaker. Then subtract it from the total length."

You can't use a calibrated tall beaker..
Maybe you can.

But everyone has different answers. :/
Did you read mine?
