Question 5

Scalars and Vectors

The diagram above shows two vectors at right angles to each other. The value of the resultant vector is

Diagram for this question
  1. A.12.0 N
  2. B.13.0 N
  3. C.14.0 N
  4. D.10.0 N.
Show the answer and explanation

Answer: D (10.0 N.)

Explanation

For perpendicular vectors, resultant = √(6.02 + 8.02) = √100 = 10.0 N.
