Explanation / Answer

We know that charges with same sign repel each and also other and charges with opposite sign attract each other
So
force on q3 due to q1 is attractive in nature.
direction:along -ve x-axis
magnitude=9*10^9*10*10^(-9)*52.5*10^(-9)/(1.705-1.055)^2=1.12*10^(-5) N

force on q3 due to q2 is repulsive in nature.
direction:along -ve x-axis
magnitude=9*10^9*32.5*10^(-9)*52.5*10^(-9)/(0-(-1.055))^2=1.38*10^(-5) N
net force is along -ve x-axis
net magnitude=2.5*10^(-5) N
