Question

Let →A=3→i+4→j. Write a vector →B such that →A≠→B, but A = B.

Answer 1

Explanation:

Such that $A \rightarrow \neq B \rightarrow$, $\text { A vector } B \rightarrow$, then $A=B$.

This is as follows:

(i) $B \rightarrow=-4 j \rightarrow+3 i \rightarrow$

(ii) $B \rightarrow=4 k \rightarrow+3 j \rightarrow$  

(iii) $B \rightarrow=4 i \rightarrow+3 k \rightarrow$

(iv) $B \rightarrow=-4 k \rightarrow+3 j \rightarrow$

• It is to be noted that the vector notation is the mathematical notation. It is used for working with the vectors that are mathematical, which may be the vector spaces’ members or geometric vectors.  

• The typographic convention used for representing the vector is upright boldface type, lower case as in the ‘v’ named vector.
