Question

Identify the conclusions which can be concluded by given statements

Statement I Some physical quantities are vectors.
Statement II All vectors have direction.
Conclusion A Some physical quantities have direction.
Conclusion B All physical quantities have direction..

• A. If only conclusion A follows
• B. If only conclusion B follows
• C. If either A or B follows
• D. If neither A nor B follows
• E. If both A and B follow

Answer 1

The correct option is A If only conclusion A follows

Statement I Some physical quantities are vectors.
Statement II All vectors have direction.
Conclusion A Some physical quantities have direction. True, Some physical quantities are vectors and vectors have direction. So some physical quantities have direction.
Conclusion B All physical quantities have direction. False, Some physical quantities are vectors and vectors have direction. So some physical quantities have direction, not all.
