Question

Three forces given by vectors 2i^ +2j^, 2i^-2j^ and - 4i^ are acting together on a point object at rest. The object
moves along the direction​

Answer 1

Explanation:

if you add all 3 vectors you get net force=0.

so the object will not move in any direction.

Answer 2

Answer:

Object at rest

Explanation:

We are given that three forces are given by the vectors

$2\hta{i}+2\hat{j},2\hat{i}-2\hat{j} and -4\hat{i}$

acting together on  a point object at rest.

We have to find the direction  in which object moves

Let $\vec{f_1}=2\hat{i}+2\hat{j}$

$\vec{f_2}=2\hat{i}-2\hat{j}$

$\vec{f_3}=-4\hat{i}$

Net force on object =$f_1+f_2+f_3$

Net force =$2\hat{i}+2\hat{j}+2\hat{i}-2\hat{j}-4\hat{i}$

Net force=$4\hat{i}-4\hat{i}=0$

Net force acting on object is zero.

Therefore, object does not move and object at rest.
