32i + 72j - 130k N & magnitude = 152.9 N where F1 = 20i + 36j – 65k N, F2 = 2i + 36j N and F3 = 10i – 65k N.
Step-by-step explanation:
F1 = 20i + 36j – 65k N,
F2 = 2i + 36j N and
F3 = 10i – 65k N
F1 + F2 + F3 = 20i + 36j – 65k + 2i + 36j + 10i – 65k N
=> F1 + F2 + F3 = 32i + 72j - 130k
Magnitude = √36² + 72² + 130² = √23380 = 152.9
