Three blocks of masses \(m_{1}, m_{2}\) and \(m_{3}\) are connected by a massless string as shown in figure on a frictionless table. They are pulled with a force \(\mathbf{T}_{3}=40 \mathrm{~N}\). If \(m_{1}=10 \mathrm{~kg}, m_{2}=6 \mathrm{~kg}\) and \(m_{3}=4 \mathrm{~kg}\), then tension \(\mathrm{T}_{2}\) will be
