A particle of mass $m$ is constrained to move on $x$-axis. A force $F$ acts on the particle. $F$ always points toward the position labeled E. For example, when the particle is to the left of $E$, $F$ points to the right. The magnitude of $F$ is constant except at point $E$ where it is zero.
The system is horizontal. $F$ is the net force acting on the particle. The particle is displaced a distance A towards left from the equilibrium position $E$ and released from rest at $t=0$
Find minimum time it will take to reach from $x=-\frac{A}{2}$ to $0.$

In order to test the strength of a rope, one end is tied to a large tree and the other end is  hitched to a team of $2$ horses. The horse pull as hard as they can, but cannot break the  rope. If the rope is untied from the tree and attached to another team of $2$ horses  with equal strength, and the two teams pull in opposite directions, the tension in the rope  will

A $100$ $Newton$ weight is suspended in a corner of a room by two cords $A$ and $B$ as shown in the figure below. The tension in the horizontal cord $A$ is ............ $N$

Two blocks of mass $2 \,kg$ and $4 kg$ are accelerated with same acceleration by a force $10 \,N$ as shown in figure on a smooth horizontal surface. Then the spring force between the two blocks will be .......... $N$ (spring is massless)

A man is pulling on a rope attached to a block on a smooth horizontal table. The tension in the rope will be the same at all points

The ends of a rope are held by two men who pulls on it with equal and opposite forces of  magnitude $F$ each. Then the tension in the rope is
