Among the given pair of vectors, the resultant of two vectors can never be 3 units. The vectors are

Options

  1. A1 unit and 2 units
  2. B2 units and 5 units
  3. C3 units and 6 units
  4. D4 units and 8 units

Correct answer

D. 4 units and 8 units

Step-by-step solution

Resultant of two vectors A and B is related as | A - B | R | A + B | For option (d), | A + B |=4+8=12 unit and |A-B|=|4-8|=4 unit
