please explain
this statement and also indicate briefly its proof if you can
A body floats in a liquid in a vessel which accelerates vertically with an acceleration less than g. the fraction immersed will neither depend on the sign nor magnitude of acceleration
BCOZ
Fraction immersed depends only on rel density , when vertical acceleration <g
[7][7]
plz help
1this was assertion reason type question
can anyone help [7][7]
please..
106See. if the vessel is accelerated, u can try to draw fbd of the body, u will see that wrt the vessel the level of body immersed will remain const. but if accn is greater than g then i dunno.
1ya thts right....it will only depend on rel acceleration.
see...we knw that g=9.8 m/s2 on earth surface....but it would made no difference
to the floating ships even if it would have been 3.4 m/s2...
assume the new g to b the net gravity acting....
hope u understood....
1as long as they are in same acceleration fraction emerged will remain the same...
remember archimedes or someone..s ....principle that weight of object=weight of displaced liquid (for floating);
now, mobject*gnew=mdisplaced water*gnew;
=>mobject=mdis. water;
so it does not depend on acc. as long as it is same on both....
1hmm..
ok i think i got it and i also think it was a dumb question
Thanks for help [1]
