Laws Of Motion

Three blocks \(\mathrm{M_1, M_2, M_3}\) having masses \(4 \mathrm{~kg}, 6 \mathrm{~kg}\) and \(10 \mathrm{~kg}\) respectively are hanging from a smooth pully using rope 1, 2 and 3 as shown in figure. The tension in the rope \(\mathrm{1, T_1}\) when they are moving upward with acceleration of \(2 \mathrm{~ms}^{-2}\) is __________ \(\mathrm{N}\) (if \(\mathrm{g}=10 \mathrm{~m} / \mathrm{s}^2\)).
