If `hati,hatj` and `hatk` are unit vectors along X,Y `&` Z axis respectively, then tick the wrong statement:

Answer

327.9 N

Explanation

Resultant force in vertical direction

`=50sqrt(3) cos 30^(@)+100+100sqrt(3) cos 30^(@)`
`=50xx3/2+100+100xx3/2=325 N`
Resultant force in horizontal direction
`=100 sqrt(3) sin 30^(@)-50 sqrt(3) sin 30^(@)`
`100 sqrt(3)/2-(50sqrt(3))/2=25sqrt(3)N`
so resultant pull`=sqrt((325)^(2)+(25sqrt(3))^(2))=327.9 N`
