An uniform thick string of length $8\, m$ is resting on a horizontal frictionless surface. It is pulled by a horizontal force of $8\, N$ from one end. The tension in the string at $3\, m$ from the force applied is ........ $N$

A smooth cylinder of mass $m$ and radius $R$  is resting on two corner edges  $A$  and $B$  as shown in fig. The relation between normal reaction at the edges $A$ and $B$  is

Write different type of common forces.

As shown in figure, a $70\,kg$ garden roller is pushed with a force of $\overrightarrow{ F }=200\,N$ at an angle of $30^{\circ}$ with horizontal. The normal reaction on the roller is $.......\,N$ $\left(\right.$ Given $\left.g =10\,m s ^{-2}\right)$

An object is subjected to a force in the north-east direction. To balance this force, a second force should be applied in the direction

A mass of $100\,kg$ is moved with uniform velocity under the influence of force $F$, then the force acting on the beam due to string connected to the ceiling ............ $N$
