$A$ man is standing on a balance and his weight is measured. If he takes a step to the left side,then his weight:

What will be the tension produced in the string $PQ$ for the given system?

For a particle to be in equilibrium,what must be the net force acting on it?

Define force. What is contact force? Write two examples of field force.

$A$ mass '$M$' is suspended by a rope from a rigid support at point '$P$' as shown in the figure. Another rope is tied at end '$Q$' and pulled horizontally with a force '$F$'. If the rope makes an angle '$\theta$' with the vertical,then the tension in the string '$PQ$' is

$A$ body of weight $2 \, kg-wt$ is suspended as shown in the figure. The tension $T_1$ in the horizontal string (in $kg-wt$) is
