Let vec a , vec b and vec c be three vectors such that | vec a|=3,| vec b|=4,| vec c|=5 and each one of them being perpendicular to the sum of the other two, find | vec a+ vec b+ vec c| .

Let vec a,vec b and vec c be three vectors such that |vec a|=3,|vec b|=4,|vec c|=5 and each one of them being perpendicular to the sum of the other two,find |vec a+vec b+vec c|

(d) answer any one question : (i) if three vectors vec a, vec b and vec c of magnitudes 3,4and5 are such that each vector is perpendicular to the sum of the other two vectors,then prove that |vec a+ vec b+vec c|= 5 sqrt 2 .

If vec(a), vec(b) and vec(c ) are three vectors such that |vec(a)| = 3, |vec(b)| = 4 and |vec(c )| = 3 and each one of them is perpendicular to the sum of the other two, then find |vec(a) + vec(b) + vec(c )| .

Let vec(a),vec(b) and vec( c ) be three vectors such that |vec(a)|=3,|vec(b)|=4,|vec( c )|=5 and each one the them being perpendicular to the sum of the other two, find |vec(a)+vec(b)+vec( c )| .

If vec (a), vec(b) and vec ( c) are three vectors of magnitude 3,4 and 5 respectively such that each vector is perpendicular to the sum of the other two vectors , prove that | vec (a) + vec(b) + vec (c ) | = 5 sqrt (2)
