Question

If a b c    0, r r r the angle between a b and r r and b c and r r are 150° and 120° respectively. Then magnitude of vectors a b c , and r r r are in ratio.

Answer 1

Answer:

a b c    0, r r r the angle between a b and r r and b c and r r are 150° a b c    0, r r r the angle between a b and r r and b c and r r are 150° and 120° respectively. Then magnitude of vectors a b c , and r r r are in ratio. 120° respectively. Then magnitude of vectors a b c , and r r r are in ratio.
