Q 11 to 23 (4A)

The value of 22.bar 4+11.5 bar 67- 33.5 bar 9 is:- 22.bar 4+11.5 bar 67- 33.5 bar 9 का मान है :

Ig |bar(a)| = 11 ,|bar(b)| = 23,|bar(a)-bar(b)| = 30 then find the angle between the vectors bar(a),bar(b) and also find |bar(a)+bar(b)| .

Solve : 0.bar( 45) + 0.bar (23)

The points 2bar(a)+3bar(b)+bar(c), bar(a)+bar(b), 6bar(a)+11bar(b)+5bar(c) are
