Question
Given below in column I are the relations between vectors a, b and c and in column II are the orientations of a, b and c in the XY plane. Match the relation in column I to correct orientations in column II.
| Column I | Column II | ||
| (a) | a + b = c | (i) |  |
| (b) | a – c = b | (ii) |  |
| (c) | b – a = c | (iii) |  |
| (d) | a + b + c = 0 | (iv) |  |
Solution
The correct match for the elements of column I and II are as follows:
| Column I | Column II | ||
| (a) | a + b = c | (iv) | |
| (b) | a – c = b | (iii) | |
| (c) | b – a = c | (i) | |
| (d) | a + b + c = 0 | (ii) | |
