Question

three forces ABC shoes in fig. lie in X Y plane. then the resultant force f is equal to a + b + c has magnitude
(1)
$\sqrt{57} n$
$\sqrt{27n }$
plz send full ans. of this que.​

Answer 1

Answer:

See friend

Here's your answer

Answer 2

Answer:

Resultant force along the x-axis:

Fx=cos60+2cos60−4sin30

=21+2×21−4×21

=21+1−2=−0.5N

Therefore 0.5 N force is required along OX
