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 points charges Q1 and Q2 placed at separation d in vacuum and force acting between them is F. Now a dielectric slab of thickness d/2 and dielectric constant K=4 is placed between them. The new force between the charges will be
