okie lemme try 1ce
a smooth ring P of mass m can slide on a fixed horizontal rod....a string tied to the ring passes over a fixed pulley and carries a block of mass m/2 as shown....at an instant the string between the ring and the pulley makes an angle 60degrees .... with the rod....INITIAL acceleration of the ring is

this is one of the tough looking simple problems :)
the fbd of the ring is to be drawn
Hint: there is no rotational mechanics involved :)
@aarthi
T varies wit theta, u hav to use ma=Tcos(theta)
and in ur eqn it is ma/2 n not ma
I am gettin g/18....Is it rite??[12][12][7][7]
[ I hav doubt in one part- My aalternative answer is g/10 hehe]
From the figure,
mg/2 -T =macos60°/2
T = macos60°
Hence,
mg/2=3macos60°/2
a=2g/3
Do U hav da answer[7][7][33]
