Variable Legend

Symbol Parameter Unit
q1 Charge 1 (q1) C
q2 Charge 2 (q2) C
r Distance (r) m

Practical Calculation Example

Problem

Calculating the result when:

  • Charge 1 (q1) = 75 C
  • Charge 2 (q2) = 75 C
  • Distance (r) = 10 m

Solution

Substituting into Eq 1.1:

Result = (8.99e9 × 75 × 75) ÷ (10 × 10)
