Solution

The correct option is B $^j -^k$
Unit vector along $x$ -axis $=^i$
So, $\to A + \to B =^i$
$(^i -^j +^k) + \to B =^i$
$\to B =^j -^k$

If →A+→B is a unit vector along x - axis and →A=^i−^j+^k, then what is →B?

The correct option is B ^j−^kUnit vector along x-axis =^i So, →A+→B=^i (^i−^j+^k)+→B=^i →B=^j−^k

If $\to A + \to B$ is a unit vector along x - axis and $\to A =^i -^j +^k$ , then what is $\to B$ ?

The correct option is B $^j -^k$
Unit vector along $x$ -axis $=^i$
So, $\to A + \to B =^i$
$(^i -^j +^k) + \to B =^i$
$\to B =^j -^k$
