Statements:
(I) All forces are energies
(II) All energies are powers
(III) No power is heat
Conclusions:
(I) Some forces are definitely not powers
(II) No heat is force
Which of the following conclusions can be definitely drawn from the statements given in the question.
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → If only (II) follows
The statements are drawn as circles: an “all” statement puts one circle inside another, and a “no” statement keeps two circles apart. Here Forces lie inside Energies, Energies inside Powers, and Heat lies outside Powers.
Conclusion (I): Some forces are definitely not powers. Does not follow. All forces are energies and all energies are powers, so every force is a power; no force can lie outside Powers.
Conclusion (II): No heat is force. Follows. Forces lie wholly inside Powers, and no power is heat, so Heat cannot touch Forces.
