A velocity 1 4 ~m / s is resolved into two components along OA and OB making angles 30^ and 45^ respectively with the given velocity. Then the component along OB is

Options

  1. A1 8 ~m / s
  2. B1 4 ( 3 -1) m / s
  3. C1 4 ~m / s
  4. D1 8 ( 6 - 2 ) m / s

Correct answer

D. 1 8 ( 6 - 2 ) m / s

Step-by-step solution

Component along OB = 1 4 30^ (45^ +30^ ) = 1 8 ( 6 - 2 ) m / s .
