Answer:
Figure shows how tension forces are acting on pulleys and mass blocks.
At mass block, we have T1 = m×g
at pulley which is clamped horizontally, T1 = T2 cos60 or T2 = 2×m×g
at pulley P, as shown in vector diagram, two tension forces T2 are acting.
Resultant of these two forces are 2×T2 × cos 60 = 2×m×g
