A steel block of mass M is being lifted by a helicopter, which is accelerating upward with an acceleration of magnitude a. The block is attached to a horizontal bar by two cables, which make angles of ${\theta }_1$ and ${\theta }_2$ w.r.t. horizontal as shown in the figure. The tension in the cable 1 in terms of M, ${\theta }_1,{\theta }_2,\mathrm{g}$ and a is
