Question

Two point charges each equal to 2 mC are 0.5 m apart. If both of them exist inside vacuum, then electrostatic force between them is:

Accepted Answer

Given:
q₁ = q₂ = 2 mC = 2 × 10⁻³ C
r = 0.5 m
k = 9 × 10⁹ N·m²/C²

Formula (Coulomb's Law):
F = kq₁q₂/r²

Calculation:
F = (9 × 10⁹) × (2 × 10⁻³) × (2 × 10⁻³) / (0.5)²

F = (9 × 10⁹ × 4 × 10⁻⁶) / 0.25

F = (36 × 10³) / 0.25

F = 1.44 × 10⁵ N

Answer: Option (A) 1.44 × 10⁵ N
