28 – Ans: A. Field lines are from +ve to –ve. The field lines of each charge will affect each other, so the field lines from the +ve charges is not straight lines here. Additionally, for the 2 +ve charges, the field lines should go in opposite direction (since the like charges repel), unlike ans B.
