For question 9
Let z = x +iy
Hence sqrt (x²+y²) - x - iy = 1 +2i
On comparison
y = -2
And
x² +y²-x = 1
sqrt (x² +4 ) = 1 +x
x² +4 = x²+ 2x +1
2x =3
x = 3/2
Hence z = 3/2 -2i
Hope it helps
Also you are advised to ask only one question per session

Three identical balls are placed on a frictionless
horizontal surface touching each other. They stick to
each other because of adhesive. Another ball of same
radius and mass m is placed over the void created by
the three balls. Find the forces applied by the balls
kept on the floor to each other if the system remains
in equilibrium.
