माना `bar(a),bar(b),bar(c)` ऐसे सदिश हैं कि `|bar(a)|=1,|bar(b)|=2,|bar(c)|=3`. यदि `bar(b)` का `bar(a)` पर प्रक्षेप तथा `bar(c)` का `bar(a)` पर प्रक्षेप समान हों तथा `bar(b)` और `bar(c)` परस्पर लम्ब हों, तो `|bar(a)-bar(b)+bar(c)|`=

If bar(a)+bar(b)+bar(c )=0 and |bar(a)|=3, |bar(b)|=5, |bar(c )|=7 and (bar(a),bar(b))= alpha , then alpha = ____

If bar(a),bar(b),bar(c) are three non zero vectors,then bar(a).bar(b)=bar(a).bar(c)rArr

([[bar(a),bar(b),bar(c)]])/([[bar(b),bar(a),bar(c)]]) =

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(c) = 3 bar(a) - 2 bar(b) then prove that [(bar(a),bar(b),bar(c))] = 0

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

If bar(a)+bar(b)+bar(c)=bar(0) then prove that bar(a)xxbar(b)=bar(b)xxbar(c)=bar(c)xxbar(a) .

If bar(a)xxbar(b)=bar(c) and bar(b)xxbar(c)=bar(a), then

bar(a),bar(b),bar(c) are three vectors such that |bar(a)|=1,|bar(b)|=2,|bar(c)|=3 and bar(b),bar(c) are perpendicular to each other.If the projection of bar(b) along bar(a) is same as that of bar(c) along bar(a) then |bar(a)-bar(b)+bar(c)| is equal to
