rakesh.........angularmomentum a force ????

oi !!!!!!!!!!!!!!!!!!! centrifugal force is nothing but pseudo force of centri..force.....experience it when u r in a rotating frame.......

did u understand! ! ! ! 1

guru !!!!!!!!!!!!!!!!!!! read again

i will answer what i know...............

when earth stops rotating...g will increase.....because g decreases( except in poles ) due to rotation....

if u want to know why...

u r in the equator ( assume ) u r rotating ...so u have centripetal acceleration (C.A)...u also have g.....part of g goes for C.A.........
its like being in the lift which is accelerating downwards....ur weight decreases.......................

hello....i was wondering ....consider a perfect circular wire..carrying a current...it produces a magnetic field..........now no current flows through it...bring a magnet near in along the axis ( or somehow, it doesn't matter ) ie, increase the flux in the loop by a constant rate...by EMI a current is induced....

now take a circular wire with a current ..it is similar to the wire having an induced current due to changing flux.....but in this case flux inside the loop doesn't change ie. time varying magnetic field wasn't produced......only a constant ( doesn't vary with time ) magnetic field is now produced .why ? why is EMI not reversible....where am i going wrong....plz answer.....................

a perfect conductor becomes ( or tends to become ) equipotential.....right ...but in a wire carrying current.( steady ) is said to have electric field inside....( we say so when deriving drift velocity ) ....but but along an electric field there is potential drop....but then how is a wire still equipotential...........i hope my query will be answered....

love
satish

here goes ur rate !!! keep blazing! ! !

im wordless..............u r gr8 !!!!!!!

dear dear.......there are no kinds of force....all forces are the same...they way they vary with time,distance..etc.......makes them different...the reaction force is equal and opposite...yes it is a force..a constant force..( as long as action is constant ).................................................then WHY THE HELL ARE U CALLING IT G FORCE, EM FORCE ????????????????

see.......reaction fore is an other normal...force...there are no diff.. kinds of force....did u understand............??

moment of inertia tells u how hard it is to rotate a body WITH ANGULAR ACCELERATION........................plz rate me

two equal forces pointing in opposite direction acting on the same body ..separated by some distance constitute a couple...............................................plz rate me

its simple ..................because moment of inertia of earth increases...the water in equator is farther from axis than in the pole....understand??

there is electric field in a live wire.then how is it equipotential

U HAVE TO STUDY ROLLING MOTION IN DETAIL..............TAKE A NICE BOOK LIE RESNICK & HALLIDAY......ELSE NOONE CAN HELP U
