Final answer:
The angle θ₁ and θ₂ are independent of each other and can be different.
Step-by-step explanation:
In electrostatics and Coulomb's Law, if mass1 = mass2, but charge1 does not equal charge2, the angle relative to the vertical of charge1 does not have a direct relationship with the angle relative to the vertical of charge2. The angle θ₁ and θ₂ are independent of each other and can be different.
