Question

i am asking if the vector a is parallel and three times that of vector b, what are there magnitudes

Answer 1

Answer:

bhai kya kiya jaye cem bhut hard hai

Answer 2

Explanation:

Let A be any vector of form = xi + yj

Therefore, B = 3( xi + yj) = 3xi + 3yj

Magnitude of B = |B| = √((3x)² + (3y)²)

= √9(x² + y²) = 3√(x² + y²)

Magnitude of A = |A| = √((x)² + (y)²)

Therefore,

|B| = 3|A|
