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 ]=?`

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 mutually perpendicular 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) .

Given four non zero vectors bar a,bar b,bar c and bar d . The vectors bar a,bar b and bar c are coplanar but not collinear pair by pairand vector bar d is not coplanar with vectors bar a,bar b and bar c and hat (bar a bar b) = hat (bar b bar c) = pi/3,(bar d bar b)=beta ,If (bar d bar c)=cos^-1(mcos beta+ncos alpha) then m-n is :

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.

Let bar(a) , bar(b) and bar(c) be vectors with magnitudes 3,4 and 5 respectively and bar(a)+bar(b)+bar(c)=0 then the value of bar(a).bar(b)+bar(b).bar(c)+bar(c).bar(a) is

If bar(a),bar(b) and bar( c ) are perpendicualr to bar(b)+bar( c ),bar( c )+bar(a) and bar(a)+bar(b) respectively and |bar(a)+bar(b)|=6,|bar(b)+bar( c )|=8 and |bar( c )+bar(a)|=10 then |bar(a)+bar(b)+bar( c )| =……………….
