1. Three point charges are positioned as follows: q₁ is at (x₁ m, y₂ m), q₂ is at (x₂ m, y₂ m), and q₃ is at (x₂ m, y₃ m). If q₁ = b₁ μC, q₂ = b₂ μC, and q₃ = b₃ μC, what is the magnitude of the force on q₂?
x₁, y₂, x₂, y₃, b₁, b₂, and b₃ are some numbers.
Answer:
|F(q₂)| = kq₂ ( (q₁/r₁²)²+(q₃/r₃²)² )⁰·⁵ =
= 8.99·10⁻³ ( (b₁/(x₂-x₁)²)²+(b₃/(y₃-y₂)²)² )⁰·⁵ N
