The electric field due to Q is in positive x and positive y direction. The field in x direction has to be balanced only by q

since q2 can has a field only in y direction

Equating the x component of electric field due to Q with the field created by q1 gives

k*400/4*cos(30) = k*q1/1.3^2

q1= 146.358 nC (the electric field will be in the negative x direction)
