Question

If a+b+c=0 and angle between vector vector and b and band c is 150 and 120. Ratio of magnitude of vector ab and c​

Answer 1

Answer:

Let →a and →b be the two unit vectors such that angle between them is 60∘. ...... Representation of vector direction sense magnitude of vector or length .... Theorem 3:If vectors →a, →b and →c are coplanar then det(→a →b →c) = 0 ... Two parallel vectors have proportional direction ratios and representation of vector r in ...

Explanation:

Answer 2

Answer:

Explanation:

For Vector a + Vector b to be 0; the vectors have to be equal in magnitude and in opposite directions. Consequently, the angle between the vectors is 180 degrees.
