A certain charge 2Q is divided at first into two parts ( q₁ ) and ( q₂ . ) Later the charges are placed at a certain distance. If the force of interaction between two charges is maximum then ( Q q₁ )

Options

  1. A( 1 )
  2. B( 04 )
  3. C( 0.5 )
  4. D( 12 )

Correct answer

A. ( 1 )

Step-by-step solution

(A) For force ( F ) to be maximum between charges ( q₁ ) and ( q₂, q₁=q₂= 2 Q 2 =Q ) Now ( Q q₁ = Q Q =1 )
