Ginni purchased an air plant holder which is in the shape of a tetrahedron.
Let A, B, C and D are the coordinates of the air plant holder where A \(\equiv \) (1, 1, 1), B \(\equiv \) (2, 1, 3), C \(\equiv \) (3, 2, 2) and D \(\equiv \)(3, 3, 4).

Based on the above information, answer the following questions.
(i) Find the position vector of \(\overrightarrow{A B} \).

(ii) Find the position vector of \(\overrightarrow{A C} \).

(iii) Find the position vector of \(\overrightarrow{AD} .\).

(iv) Area of \(\Delta A B C\) = 

(v) Find the unit vector along \(\overrightarrow{AD} .\)

Teams A, B, C went for playing a tug of war game. Teams A, B, C have attached a rope to a metal ring and is trying to pull the ring into their own area (team areas shown below).
Team A pulls with force F₁ = \(\hat{4}+\hat{0} \hat{j}\) KN
Team B ⟶ F₂ = \(-2 \hat{i}+4 \hat{j}\) KN
Team C ⟶ F₃ = \(-3 \hat{i}-3 \hat{j}\) KN

Based on the above information, answer the following questions.
(i) Which team will win the game ?

(ii) What is the magnitude of the teams combined force ?

(iii) In what direction is the ring getting pulled?

(iv) What is the magnitude of the force of Team B?

(v) How many KN force is applied by Team A?
