Question

The forces F. F2, F3.... acting on an object are in equilibrium if the resultant force is the zero vector. F1+F2+F3 +Fn-0 The forces shown in the graph on the right are acting on an object.8 a. Find the resultant force b. What additional force is required for the given forces to be in equilibrium? a. The resultant force is -6j (Simplify your answer. Type your answer in terms of i and j) b. The additional force required for the given forces to be in equilibrumis (Simplify your answer. Type your answer in terms of i andj) 0 Enter your answer in each of the answer boxes

Explanation / Answer

F1 = <-6,0>
F2 = <-1,4>
F3 = <7,-6>
F4 = <0,-4>

Adding 'em up :

F1+F2+F3+F4 is :

<-6-1+7+0 , 0+4+-6+-4>

<0 , -6>

So, resultant force is :
-6j

------------------------------------------------------------------

For equilibrium,
we need +6j force to cancel it out

So,
6j ----> second ans
