If `|bar(a)+bar(b)|=1`,`|bar(a)-bar(b)|=7`,`|bar(a)|=4` then `|bar(b)|`

If (bar(a),bar(b))=(pi)/(6),bar(c) is perpendicular to bar(a) and bar(b),|bar(a)|=3,|bar(b)|=4,|bar(c)|=6 then |[bar(a)bar(b)bar(c)]|

If |bar(a)|=|bar(b)|=1 and |bar(a)timesbar(b)|=bar(a)*bar(b) , then |bar(a)+bar(b)|^(2)=

If |bar(a)|=3,|bar(b)|=4,|bar(a)-bar(b)|=5 then |bar(a)+bar(b)|=...

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

If bar(a),bar(b) and bar(c) are perpendicular,bar(c)+bar(a),bar(b)+bar(c) and bar(a)+bar(b)+ respectively and if |bar(a)+bar(b)|=6,|bar(b)+bar(c)|=8 and |bar(c)+bar(a)|=10 then |bar(a)+bar(b)+bar(c)| is equal to

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

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

If bar(p)=bar(a)+bar(b),bar(q)=bar(a)-bar(b),|bar(a)|=|bar(b)|=r , then |bar(p)timesbar(q)| =
