Question

two force of 4 dyne and 3 dyne act upon a body. the resultant force on the body can only be

Answer 1

R =√( 4² + 3² )

R= √25 

R= 5 dyne 

Answer 2

Hey there !!!!!

If F₁ and F₂ are two forces acting on a body

Then resultant force R= √(F₁² + F₂²)

Here F₁=3 Dyne F₂=4 dyne

R=√(3²+4²)=√9+16=√25=5 Dyne

Hope this helped you............
