Two forces F subscript 1 end subscript and F subscript 2 end subscript act on a thin uniform elastic rod placed in space. Force F subscript 1 end subscript acts at right end of the rod and F subscript 2 end subscript acts exactly at centre of the rod as shown (both forces act parallel to length of the rod).
i) F subscript 1 end subscript causes extension of rod while F subscript 2 end subscript causes compression of rod.
ii) F subscript 1 end subscript causes extension of rod and F subscript 2 end subscript also causes extension of rod.
iii) F subscript 1 end subscript causes extension of rod while F subscript 2 end subscript does not change length of rod.
The correct order of True / False in above statements is
