Question

the resultant of two force 10 N and 15 N acting along +x and -x axes respectively is ​

Answer 1

Answer:

$5 \: newtons \: \: along \: \: - ve \: x \: axis.$

Explanation:

$resultant \: force = \sqrt{ {(10)}^{2} + {(5)}^{2} + 2(10)(5) \cos(\pi) } \\ \\ = \sqrt{100 + 25 - 100 } \\ \\ = 5 \: units \\ \\ \\along \: - ve \: \: x \: \: axis.$
