There are four forces acting at a point $P$ produced by strings as shown in figure, point $P$ is at rest. The forces $F_1$ and $F_2$ are respectively:-
- A$\frac{1}{\sqrt 2}N,\frac{3}{\sqrt 2}N$
- B$\frac{3}{\sqrt 2}N,\frac{1}{\sqrt 2}N$
- C$\frac{1}{\sqrt 2}N,\frac{1}{\sqrt 2}N$
- D$\frac{3}{\sqrt 2}N,\frac{3}{\sqrt 2}N$

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 $t=0$
Velocity-time graph of the particle is

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
