The figure below depicts two boxes connected to each other by a massless string. Determine the magnitude of the tension force in the string if the motion of the boxes is downwards on the inclined plane.

The figure shows a 250 g slab placed on a 950 g frictionless wedge structure. The whole assembly rests on level ground. Determine the normal reaction experienced by the wedge if the slab was sliding downwards on the inclined structure.

A box of textbooks (box T) and a crate of laboratory equipment (crate L) are connected by a durable nylon rope and slide down an inclined plane at an angle $\theta =45°$ to the horizontal. The masses of both boxes are $m_T=m_L=10.0\mathrm{kg}$. The coefficients of friction for the box and the crate are ${\mu }_T=0.30$ and ${\mu }_L=0.40$, respectively. Calculate the tension in the rope as the system slides down the incline.
