Answer:
The magnitude of of other vector B can be calculated by
B=[tex]\sqrt{R^{2}-A^{2} }[/tex]
Explanation:
Suppose we have 2 initial vectors A and B. The resultant vector is R
The magnitude of resultant vector will be,
[tex]R^{2} =A^{2} +B^{2}[/tex]
[tex]B^{2} =R^{2} -A^{2}[/tex]
Thus,
B=[tex]\sqrt{R^{2}-A^{2} }[/tex] will be the formula for finding the other initial vector B
⇒
⇒
Hence, the correct relation for B will be .
