Answer 1

Yes, a body can remain in position of rest, when external forces are acting on it, provided the vector sum of all the external forces is zero. That is when the resultant of all the forces is a net zero force. Yes it can if: Forces actingon the body in such a way that resultant force acting on the body is zero.
