Question

Statement 1: In `"Delta"A B C , vec A B+ vec A B+ vec C A=0` Statement 2: If ` vec O A= vec a , vec O B= vec b ,t h e n vec A B= vec a+ vec b`
A. Both Statement I and Statement II are correct and statement II is the correct explanation of statement I
B. Both statement I and statement II are correct but statement II is not the correct explanation of statement I
C. Statement I is correct but statement II is incorrect
D. Statement II is correct but statement I is incorrect

Answer 1

Correct Answer - C
In `DeltaABC,AB+BC=AC=-CA`
or `AB+BC+CA=0`
OA+AB=OB is the triangle law of addition.
Hence, statement 1 is true and statement 2 is false.
