Question

A beaker of mass
50 g with 262 g of
water in it is kept on
a weighing machine.
A uniform hollow
brass ball of total
volume 367 cc is
inserted into the
water in the beaker.
It is observed that
the ball floats on
water. The weighing
machine now reads
400 g. The density of
brass is 8 g/cc while
that of the air inside
the brass ball can be
neglected Thickness of the brass used to prepare the ball will be close to

3mm
2mm
1mm
4mm​
