Answer
The charge on the positively charged spheres are equal in all 3 example
$q1=q2=q3$
Work Step by Step
q1: The positively charged sphere loses 5 electrons to the negatively charged sphere to reach equilibrium
$6e - 5e = 1e$
q2: The positively charged sphere loses 1 electron to the negatively charged sphere to reach equilibrium
$2e - 1e = 1e$
q3: The positively charged sphere loses 13 electrons to the negatively charged sphere to reach equilibrium
$14e - 13e = 1e$
Therefore, $q1=q2=q3$
