Which force act on body first action or reaction ?
Two masses $m$ and $M$ are attached to the strings as shown in the figure. If the system is in equilibrium, then

A body of mass $m$ hangs at one end of a string of length $l$, the other end of which is fixed. It is given a horizontal velocity so that the string would just reach where it makes an angle of $60^o$ with the vertical. The tension in the string at mean position is
A book is lying on the table. What is the angle between the action of the book on the table and the reaction of the table on the book ............ $^o$
A block of $\sqrt{3}\,kg$ is attached to a string whose other end is attached to the wall. An unknown force $F$ is applied so that the string makes an angle of $30^{\circ}$ with the wall. The tension $T$ is $...........\,N$ :(Given $g =10\,ms ^{-2}$ )
