Answer:

Triangle law of vector addition:

If two vectors of a same physical quantity are represented in magnitude and direction by the two sides of triangle, then their Resultant is represented in magnitude and direction by the third side.

Note:

Graph is used for finding the resultant vector by the triangle law of vector addition.

e.g. ( Question in the attachment )

Let A and B be the two forces of 40 N and 50 N respectively ( angle between the vectors is given if question is to be solved by triangle law of vector addition. )

Steps and Method:

  1. Take 5 N = 1 unit ( can take any measures )
  2. Draw the line for vector A as per the given direction (refer attachment)
  3. The starting point is tail and the point on the end is head.
  4. Draw the vector for B by starting it's tail from head of vector A as per given direction.
  5. Join tail of vector A to the head of vector B by making a line .
  6. Mark head of vector C at line joined at head of vector B.
  7. Measure vector C which is formed joining tail of vector A and head of vector B.
  8. Convert it in to N ( assumed in starting )
  9. Direction of the resultant vector will be same formed while joining tail of vector A and head of vector B.
