A weight can be hung in any of following four ways by using same string. In which case is the string more likely to break is :-
$A$
$B$
$C$
$D$
When a body is stationary
Write condition for equilibrium when two force act on a particle.
In the figure shown, a balloon is pressed against a wall. It is in equilibrium and maximum compresed state.$\vec F_1\,=$ force of balloon on hand of man $;$ $\vec F_2\,=$ force of balloon on wall $;$ $\vec F_3\,=$ friction $;$ $\vec F_4=$ weight of balloon. Choose the correct statement.
Figure shows $(x,\, t)$, $(y,\, t)$ diagram of a particle moving in $2-$ dimensions.
If the particle has a mass of $500\,g$, find the force (direction and magnitude) acting on the particle.
Figure shows two cases. In first case a spring (spring constant $K$ ) is pulled by two equal and opposite forces $F$ at both ends and in second case is pulled by a force $F$ at one end. Extensions $(x)$ in the springs will be
