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

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

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

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.

bar a, bar b, bar c are three vectros, then prove that: (bar a xx bar b) xx bar c = (bar a. bar c) bar b-(bar b. bar c) bar a.

(d) answer ANY one question :1. bar a, bar b and bar c be three vectors such that bar a +bar b+ bar c =0 and |bar a|=1, |bar b|=4,|bar c |=2 . Evlautae bar a.bar b + bar b.bar c+bar c.bar a .

if bar a+2 bar b+3bar c=bar 0 then bar axxbar b+bar b xx bar c+bar cxx bara = lambda (bar b xx bar c) ,where lambda=

bar(a)=2hati+hatj-2hatk and bar(b)=hati+hatj . The vector bar( c ) is such that bar(a)*bar( c )=|bar( c )|,|bar( c )-bar(a)|=2sqrt(2) and the angle between bar(a)xx bar(b) and bar( c ) is 30^(@) then |(bar(a)xx bar(b))xx bar( c )| = …………

If bar(a) is a perpendicular to bar(b) and bar(c), |bar(a)|=2, |bar(b)|=3, |bar(c)|=4 and the angle between bar(b) and bar(c) is (2pi)/(3) then |[bar(a) bar(b) bar(c)]| =

If bar r=l(bar b xx bar c)+m(bar c xx bar a)+n(bar a xx bar b) and [bar a bar b bar c]=2 , then l+m+n is equal to
