" 10) "3quad ([9.),bar(a),bar(b)" and "bar(c)" are mutually perpendicular "],[" unit vectors then "[bar(a)bar(b)bar(c)]=]

If bar(a),bar(b),bar(c ) are mutually perpendicular unit vectors, then find [bar(a)bar(b)bar(c )]^(2) .

If bar(a),bar(b) and bar(c) are mutually perpendicular vectors then [bar(a)bar(b)bar(c)]=

If a,b and c are mutually perpendicular vectors,thenprove that [bar(a)bar(b)bar(c)]^(2)=a^(2)b^(2)c^(2)

If for unit vectors bar(a) and bar(b),bar(a)+2bar(b) and 5bar(a)-4bar(b) are perpendicular to each other, then (bar(a)^^bar(b))=

Let bar(a),bar(b) be two non zero vectors such that vectors 3bar(a)-5bar(b) and 2bar(a)+bar(b) are mutually perpendicular. If bar(a)+4bar(b) and bar(b)-bar(a) are also mutually perpendicular then the cosine angle between bar(a) and bar(b) is

If bar(a),bar(b),bar( c ) and bar(d) are coplanar vectors then (bar(a)xx bar(b))xx(bar( c )xx bar(d)) = …………..

if bar(a),bar(b),bar(c) are any three vectors then prove that [bar(a),bar(b)+bar(c),bar(a)+bar(b)+bar(c)]=0

If bar(a),bar(b),bar (c ) are pair wise mutually perpendicular vectors of equal magnitude , then the angle wisv bar(a)+bar(b)+bar (c ) is

If bar(a),bar(b) and bar(c) are non-coplanar unit vectors such that bar(a)times(bar(b)timesbar(c))=(1)/(sqrt(2))(bar(b)+bar(c)) ],then which of the following statements are correct A. (bar(a),bar(c))=(3 pi)/(4) B. (bar(a),bar(b))=(3 pi)/(4) C. (bar(a),bar(b)+bar(c))=(pi)/(2) D.(bar(b),bar(c))=0

IF bar a , bar b , bar c are mutually perpendicular vectors having magnitudes 1,2,3 respectively then [ bar a + bar b + bar c " " bar b - bar a " " bar c ]=?
