If `bar(a)+bar(b)+bar(c)=bar(0)` then `bar(a)timesbar(b)=`

If bar(a)+2bar(b)+3bar(c)=bar(0) then bar(a)xxbar(b)+bar(b)xxbar(c)+bar(c)xxbar(a)=

If [bar(a) bar(b) bar(c)]=2 ,then [2(bar(b)timesbar(c))(-bar(c)timesbar(a))(bar(b)timesbar(a))] is equal to

If [bar(a) bar(b) bar(c)]=2 then [2(bar(b)timesbar(c))(bar(-c)timesbar(a))(bar(b)timesbar(a))] is equal to

bar(a),bar(b),bar(c) are vectors such that [bar(a)bar(b)bar(c)]=4 then [bar(a)timesbar(b) bar(b)timesbar(c) bar(c)timesbar(a)] is (A) 16 (B) 64 (C) 4 (D)8

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

Let bar(a),bar(b),bar(c) be three non-zero vectors such that bar(a)+bar(b)+bar(c)=0 .Then lambda(bar(a)timesbar(b))+bar(c)timesbar(b)+bar(a)timesbar(c)=0 where lambda is

Three vectors bar(a) , bar(b) and bar(c) are such that [bar(a)timesbar(b)=3bar(a)timesbar(c) .Also |vec a|=|bar(b)|=1 and |bar(c)|=(1)/(3) .If the angle between bar(b) and bar(c) is 60^(@) ,then.

If bar(a)+bar(b)+bar(c), then

If |bar(a)| =2 and |bar(b)|=3 and bar(a) .bar(b)=0 then |(bar(a)times(bar(a)times(bar(a)times(bar(a)timesbar(b)))))| (A) 16 (B) 32 (C) 48 (D) 0

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