Question

Vectors ā ,b,c,dare given by
a=i +j+k, b = 2î +3j,c= 3i +5j– 2k, d=k-j.Prove that the vectors
(b - ā) and (d-c) are parallel and find the ratio of their moduli.
9) are collinear​

Answer 1

Answer:

Correct option: (B) (4î + 5ĵ) ms–1 Explanation: V = Vo + at Vo = 2î + 3î t = 2î a = î + ĵ V = (2î + 3ĵ) + 2(î + ĵ) = 4î + 5ĵ m/s
