Question

1. Find the modulus and direction of the resultant force of the forces F1 and F2, the directions of which form the angle 90⁰ between them, and their modulus are

F1 = 12N and F2 = 8N.

Answer 1

$F_t=\sqrt{12^2+8^2}=14.4\ (N)$

$\alpha=\tan^{-1}(\frac{12}{8})=56.3°$ from the direction of force $F_2$ . Answer
