In a tug of war, each of the two teams apply $1000 \mathrm{N}$ force at the ends of a rope which is found to be in equilibrium. The tension in the rope is,

A mass $M$ is suspended by a rope from a rigid support at $A$ as shown in the figure. Another rope is tied at the end $B$ and it is pulled horizontally with a force $F$. If the rope $AB$ makes an angle $\text{θ}$ with the vertical in equilibrium, then the tension in the rope $AB$ is

A flexible chain of weight $W$ hangs between two fixed points $A$ and $B$ at the same level. The inclination of the chain with the horizontal at the two points of support is $\text{θ}$. What is the tension of the chain at the endpoint? 

The pulleys and strings shown in the figure are smooth and of negligible mass. For the system to remain in equilibrium, the angle $\text{θ}$ should be

The normal reaction on a body placed in a lift moving up with a constant acceleration of $2 \mathrm{m} {\mathrm{s}}^{-2}$ is $120 \mathrm{N}$. Mass of the body is:

(Take $g=10\mathrm{ }\mathrm{m} {\mathrm{s}}^{-2}$)
