The Attempt at a Solution
Suppose tension in the left string mAM be T_{1} and tension in the right string mBM be T_{2} .When the particles cross each other then the angle made by string mA and mB with vertical is α and that made by AM and BM be β . The speed of m is u and that of M is v .
The work done by tension would be zero , so
(T_{1}cosα)u + (T_{1}cosβ)v  (T_{2}cosα)u + (T_{2}cosβ)v = 0
By symmetry I believe the tensions should be equal so if I put T_{1} = T_{2}
I get , (cosα)u = (cosβ)v .
But now I do not think α is equal to β when the masses cross each other .
Am I thinking correctly ?
Thanks
