Question

One of the rectangular components of a force of 50 N is 30 N. The other rectangular component will be :

• A. 40 N
• B. 30 N
• C. 35 N
• D. 45 N

Answer 1

The correct option is A 40 N

For rectangular components,

$F=\sqrt{F_x^2+F_y^2}$

Let $F=50Nand{F}_x=30N$

${50}^2={30}^2+F_y^2$

$F_y^2=2500-900=1600$

$F_y=40N$

Option A is correct.
