Explanation:

Looking at the charges, basically, the net force of the charge q1 is the sum of charges q2 and q3.

When 2 charges are opposite, the force will be attractive but if they are same, then the force will be repulsive.

Thus, the order of the forces is;

I) Largest: q1= +1nC, q2= -1nc, q3= -1nc and (q1= -1nC, q2= +1nc, q3= +1nc)

II) Second largest is: q1= +1nC, q2= -1nc, q3= +1nc

III) Third largest: q1= +1nC, q2= +1nc, q3= -1nc

IV) Smallest: (q1= -1nC, q2= -1nc, q3= -1nc) and (q1= +1nC, q2= +1nc, q3= +1nc)

the first step is making objective observations.

they have to be based on a certain event and can be confirmed by others if it is right or not.

convex lenses are thicker at the middle. rays of light that pass through the lens are brought closer together (they converge). a convex lens is a converging lens. when parallel rays of light pass through a convex lens the refracted rays converge at one point called the principal focus.
