Given that q₁+q₂=q . For what ratio q₁ / q₂ will the force between q₁ and q₂ be maximum ?

Options

  1. A0.25
  2. B0.5
  3. C1
  4. D2

Correct answer

B. 0.5

Step-by-step solution

F= q₁ q₂ 4 ₀ r^2 = q₁ (q-q₁ ) 4 ₀ r^2 For maximum force between q₁ and array rlrl & d F d q₁ & =0 & q-2 q₁ & =0 or & q₁ & = q 2 & or q₁ q =0.5 array
