two amall balls having equal positive charge Q on each are suspendd by two insulating string of equal lenghts L from a hook. I the setup is taken in the satelite then angle theta between the two strings at equilibrium is. also find the tension in each string

Inside a sattelite the balls wont feel gravity.No mg will act on them.So due to electric repulsion they would tend to go as far from each other as possible.That will occur when they are horizontally on opposite sides or angle=180 degree.
And the tensional force will only be this force of coulombic repulsion.
T=Q2/4piepsilon(2L)2

The answer is 180°
because the same charged balls stands where the electric attrection is lowest.
