A body of superdense material with mass twice the mass of earth butsize very small compared oto the size of earth starts from rest from h<<R above the earth's surface. It reaches earth in time
11Yes, akand. It is pronounced as " baadhonoo" and i'm not telling the meaning!
1ohh cmon aragorn !!!!
bt its nt ur fault Mr AKAND forced ,u if i m rite
1yup vishal.................from earths frame of reference , earth is rest and d mass comes within time t=√h/g..
and from d mass's frame of reference earth will cum toward it.....i think it shud be same or there cud be a difference....(i dunno this).
but if i see from d frame of ref of d universe....then both will move a bit(as h<<R), so time will be literally less than √h/g.......
11If you were to take earth as the frame, will net acceleration be 4g?
Because acc. of body towards earth is 2g and that of earth towards body too is 2g. So acc. as taken frm earth is 2g+2g=4g.
Correct?
1cum on.........i was just learning tamil and these guyz are teachin me bad words..............waaaahhhh
3when two particles under mutual attractive force will they meet only at the center of mass of the twoo particles
1a good quote:::
TRUE FRIEND IS 1 WHO
1.)FORGIVES U B4 U SAY SORRY...
2.)UNDERSTANDS B4 U EXPLAIN....
3.)WAITS 4EVER WEN U SAY 1MIN.........
4.)STAYS ON WHEN U SAY LEAVE ME ALONE......
SO UNDERSTAND DIS PROBLEM B4 I EXPLAIN IT..........

yup aragorn i m getin somthing like this in ma expression
i usedforce
F btw masses=2GM2/(h+R+R')2
1SANKARA PANDI...... STARTED D SAME THING AGAIN...........THINK IN SOME OTHER (THETA)
3in classical mechanics the time interval between two events is the same for all reference fram
3in classical mechanics the time interval between two events is the same for all reference fram
1aaaaaaaaaaaahhhhhhhhhhhhhhh.............im confused.........i thought this was a simple question..........ARE MY BASICS THAT BAD????????????
1HEY .. VISHAL SORRY.. I M SERIOUS NOW.. AND U VE TAKEN MA JOB NOW.......??????????
1SOULDNT the force be f=M(2M)/(r+h)2????????? and if h is neglected then everythings fine.......

@ram & aragorn
frm where dat R came
its h dat is ditance btw 2 objects
*****sry R has to b there
1ya vishal shudnt tht be distance between d centre of masses of 2 objects??? So it is R+h
1@ sankar
which 2 events dude only 1 event is taking place here
1ya thts true sanki.........thts in classsical mechanics...........we wer just talkin bout relative refe........as both r moving we need to take relatively.......
1sry guys just carried away a bit its(h+R+R')
R'=radius of other planet
1CAN ANYONE PLZ GET A SMALL SKETCH OF IT?????????????????
1THEN THERE LL B NO CONFUSION ON WAT IS R N WAT IS H??????????????????????????????????????????????????????????????????????
1and vishal isnt R' negligible(its given in d ques)..........its very small...........so R+R'+h is almost R+0.000000000000001. which is almost equal to R
11@ vishal
THe other one's not a planet. It's size is actually negigible when compared to earth's size. Is made up of superdense material!
