Answer 1

B)
`R= √((40N)^2+(30N)^2)`

Step-by-step explanation:

Given
`\sum Fx=40N\ \ \ \ \ \ \ \ \ \sum Fy=30N`

As the forces are on X and Y-axis. We can see the angle between the forces is 90°

Using vector addition formula. Since the angle between the forces is 90°

`R=√(\sum (Fx)^2+\sum (Fy)^2)`

`R= √((40N)^2+(30N)^2)`
