13v all are waiting for ur solution earendil... [3] [3]
well sankara... i dunno exactly d method but u can solve it by force method, i guess... by equating d centripetal force to __________ . [unable to fill up dat blank [2]]
3equating the centripetal force to the force of attraction
but i have pbm in finding the ang.momentum i have a great pbm in using calculus to physics..
can u help me in finding the ang.momemtum part..
1the first idea i get is dA/dt = L/2m
the thing here is to find the areal velocity
find the velocities at r1 and r2
areal velocity is give n by 1/2(v1r1) and 1/2(v2r2)
