In the figure the reading of the spring balanced will be $......\,N$ $\left[ g =10 m / s ^2\right]$

Which of the following groups of forces could be in equibrium

The restoring force of a spring with a block attached to the free end of the spring is represented by

What will be the acceleration of blocks and tension in the string connecting the blocks $2\,kg$ and $5\,kg$ for the given figure :-

There are four forces acting at a point $P$ produced by strings as shown in figure. Which is at rest ? Find the forces $F_1$ and $F_2$.
