Vector resolution and addition
Sir please send me the answers with the reasons and steps
- the drawing on the left shows two vectors A and B, and the drawing on the right shows their components.
The scalar components of these vectors are:
When the vectors A and B are added, the resultant vector is R, so that R = A + B. What are the x– and y-components of R?
- the displacement vectors A and B, when added together, give the resultant vector R, so that R = A + B. Use the data in the drawing to find the magnitude R of the resultant vector and the angle q that it makes with the +x axis.
In the first question as you can see that the X components (Ax and Bx being equal and opposite will cancel each other and therefore the X com ponent of the resultant is zero.
The Y components will add up and therefore the Y component of resultant = 3.4+3.4 = 6.8 m and this itself is the magnitude of the resultant as the X components have canceled out.
Hnit for Answer to the second question
