The whole set up is taken in a satellite into space where there is no gravity (state of weightlessness). Then angle between the two strings is.

Two small balls having equal positive charges Q( coulomb) on each are suspended by two insulating strings of equal length L(metre) from a hook fixed to a stand. The whole set up is taken in a satellite into space where there is no gravity (state of weightlessness). Then angle between the two strings is.

Two free charges q and 4q are placed at a distance d apart. A third charge Q is placed between them at a distance x from charges q such that the system is in equilibrium. Then
