A small insulating charged ball, with charge q $=5$C and mass m $=0\mathrm{.}6$kg hangs vertically from an insulating thread. When placed in a uniform and horizontal electric field, the ball moves towards the right until the thread forms an angle alpha $=20$ degrees. What's the magnitude and direction of the electric field? $($g $=9\mathrm{.}8$N $/$ k $*$ g$)$
