What is the resultant of two vectors of 3unit and 4unit acting at a point at an angle of 45degree, with each other.And find the direction
To find the resultant of two vectors acting at a point, we can use the graphical method called the parallelogram method.
Step 1: Draw the two vectors on a graph paper. Let's call the vectors A and B, with magnitudes of 3 units and 4 units, respectively. Start by drawing vector A as a line segment of 3 units in the desired direction.
Step 2: Draw vector B starting from the endpoint of vector A. The angle between vector A and vector B is 45 degrees. So, draw vector B at an angle of 45 degrees with vector A, and make its length 4 units.
Step 3: Complete the parallelogram by drawing lines parallel to the vectors originating from the opposite endpoints.
Step 4: Draw the resultant vector as a line segment from the common origin (point O) to the opposite corner of the parallelogram.
Step 5: Measure the length of the resultant vector on the graph paper using a ruler. This length will give you the magnitude of the resultant vector.
Step 6: Measure the angle between the resultant vector and vector A. This angle will give you the direction of the resultant vector.
Using the parallelogram method, you can find the magnitude and direction of the resultant vector of 3 units and 4 units acting at an angle of 45 degrees with each other.
If the 4-vector is <4,0> then the 3-vector is <3/√2,3/√2>
