यदि `|bar(a)+bar(b)|=|bar(a)-bar(b)|` हो, तब `bar(a)` तथा `bar(b)` समान्तर होंगे |

If |bar(a)+bar(b)|<|bar(a)-bar(b)| then (bar(a),bar(b)) is

For non -zero vectors a and b if |bar(a)+bar(bar(b))|<|bar(a)-bar(b)|| then bar(a) and bar(b) are

(bar(a)+2bar(b)-bar(c))*(bar(a)-bar(b))xx(bar(a)-bar(bar(c)))=

If |bar(a)|=3,|bar(b)|=4 and |bar(a)+bar(b)|=5, then |bar(a)-bar(b)| is equal to

If |bar(a).bar(b)| = |bar(a) xx bar(b)| & bar(a). bar(b) lt 0 , then find the angle between bar(a) and bar(b) .

If |bar(a)xx bar(b)|^(2)+|bar(a).bar(b)|^(2)=144 and |bar(a)|=4 , then |bar(b)| is equal to ……………….
