Question

if several forces act in different direction on a body,in which direction will the body move

Answer 1

The body moves in the direction in which the force is applied more on that body.which makes the body to move.but if the forces are equal in all directions then the body doesn't move in any direction it stays at rest position.

Answer 2

Force is a vector quantity.
And thus, force follows the laws of vector addition and subtraction and, thus the body will move in the direction where the direction of the resultant force or the net force comes out to be so, that an acceleration is generated in that direction for the body to move.
