Explanation:

The angle between the threads is determined by the balance of forces acting on the charges. The charges will repel each other and the threads will become taut. The angle between the threads will depend on the magnitude and distance between the charges.

When the system is taken to space, there are no external forces acting on the charges and they will move apart due to their mutual repulsion. As they move apart, the angle between the threads will increase until it reaches 180 degrees.

This can be explained mathematically using Coulomb's law, which states that the force between two charges is proportional to the product of their charges and inversely proportional to the square of the distance between them. As the charges move apart, the force between them decreases and the angle between the threads increases.

Therefore, the correct answer is option 'A', 180 degrees.

There is gravitational field on earth, so if we hang the two same charges there will be an interaction of vertical gravitational field and horizontal electric field. The system will achieve equilibrium by creating a certain angle between the threads and hence the vertical and horizontal components of forces will balance. But in space, there is no gravity. So the charges will be at 180-degree separation.
