Question

[tex]\mathfrak {50/ points!!!}[\tex]
Two forces of 5N and 10N acting at a point have an angle of 120° between them. Find the magnitude and direction of the resultant force.

Answer 1

Step by step explanation:

concept:

use vector addition:

use Parallelogram law of vector addition

then ,

net force

$= \sqrt{(f1) {}^{2} + (f2) {}^{2} + 2f1f2 \cos(120) }$

Answer 2

Answer:

here is ur ans....

Explanation:

F=√(f1)^2+(f2)^2+2(f1)(f2)cos120°

=√100+25+2(10)(5)(-1/2)

=√125-50

=√75

hope its help you...
