Question
Objects A and B each of mass m are connected by light inextensible cord. They are constrained to move on a frictionless ring in a vertical plane as shown in figure. The objects are released from rest at the positions shown. The tension in the cord just after release will be
Options
A.mg √2
B.
C.
D.
Solution
On block B :
mg − T cos 45o = ma ...(i)
on block A :
T cos 45o = ma ...(ii)
by equation (i) and (ii)
T =
