Question

find the resultant of two forces one 6newton due east and other 8 newton due north​

Answer 1

Resultant = under root(8^2 + 6^2 + 2 × 8 × 6 × cos theta)

where theta is 90°

then Resultant = under root(8^2 + 6^2)

Resultant = under root(64 + 36)

Resultant = under root(100)

Resultant = 10 N

Answer 2

resultant between 2force is

root a square +bsquare×2aboso

(o is angle between victors)

root 6hole square +8whole square+2×6×8cos90degree

root36+64+2×6×0
