Question

Which of the options will form a knot when both the ends are pulled outward?

• A.

  

• B.

  

• C.

  

• D.

  

Answer 1

The Correct Option is B, D

In determining which figures will form a knot when both ends are pulled outward, we need to analyze how the loops and crossings are arranged in each figure.

When a rope forms a knot, pulling on both ends usually results in the loops tightening around one another, maintaining the entanglement.

Let's assess the figures:

Fig 1	Upon pulling, the ends do not interlock or twist around each other sufficiently, hence no knot forms.
Fig 2	This figure shows a structure where pulling the ends will cause the loops to clasp onto each other, forming a knot.
Fig 3	The layout of loops in this figure will likely unravel rather than form a knot when tension is applied.
Fig 4	This figure's loops are arranged to interlock when tension is applied, resulting in a knot.

Thus, the figures that will form a knot when the ends are pulled are:

• Fig 2
• Fig 4
