Question

if a force of 5n and 3n are acting on am object in opposite direction than calculate the result and force​

Answer 1

Answer:

Let two force vector be F1 and F2 whose magnitude is given

F1=5N, F2=3N and angel between them is θ=900.

Let Fr is the resultant of two force whose magnitude is obtained by

Fr=F21+F22+2F1F2cosθ−−−−−−−−−−−−−−−−−−√

⇒Fr=52+33+2×5×3×cos(900)−−−−−−−−−−−−−−−−−−−−−−−−√

⇒Fr=25+9+0−−−−−−−−√(∵cos(900=0))

∴Fr=34−−√=5.8N

The resultant force Fr→ acts at an angle 450 to F1 and F2
