Answer:
[tex]F_R=\sqrt{2} \ pound.force[/tex]
Explanation:
Given that there are two force of 1 pound each at right angles to each other.
The from the vector law of addition:
[tex]F_R=\sqrt{F_1^2+F_2^2}[/tex]
where:
[tex]F_R=[/tex] resultant force
[tex]F_1\ \&\ F_2[/tex] be the two of the forces to be added.
[tex]F_R=\sqrt{1^2+1^2}[/tex]
[tex]F_R=\sqrt{2} \ pound.force[/tex]
