Two point charges q and q in vacuum are located at the points A(a, 0) and B( a, 0) in the xy plane. Assume that a 0 and q 0 . Select the correct statement(s).

Options

  1. AIf the midpoint between the charges is fixed, then the maximum force of attraction is 1 4 ₀ [ q 2 a ]^2 .
  2. BIf the sum of the charges is fixed, then the maximum force of repulsion between the charges is 1 4 ₀ [ q a(1-
  3. CIf the mid point between the charges is fixed, then the maximum force (attractive or repulsive) happens when t
