Three different forces act on an object. They are: F₁ = (-8, 7) F₂ (8, 1) F3 = (-4, 3) - Find the net force Fnet on the object (the sum of the forces) F net = Find what fourth force, F4 would need to be added so the object feels no force, that is, so Fnet F₁- = 0

Question
**Physics: Understanding Forces on an Object** Three different forces act on an object. They are: \[ \vec{F_1} = \langle -8, -7 \rangle \] \[ \vec{F_2} = \langle 8, 1 \rangle \] \[ \vec{F_3} = \langle -4, 3 \rangle \] **Task 1: Find the Net Force** Calculate the net force \(\vec{F_{\text{net}}}\) acting on the object, which is the sum of the forces. \[ \vec{F_{\text{net}}} = \] **Task 2: Achieving No Net Force** Determine what fourth force, \(\vec{F_4}\), would need to be added so the object feels no force, meaning \(\vec{F_{\text{net}}} = 0\). \[ \vec{F_4} = \] **Question Help:** - [Video](#) - [Message Instructor](#) [Submit Question]
