Can a body remain at rest position when external forces are acting on it?

The distance traveled by a body is directly proportional to time Is any external force acting on it ?

If no external force acts on a system

If no external force acts on a body, it will

The velocity of centre of mass of the system remains constant, if the total external force acting on the system is.

Assertion : An external force is required to keep a body in motion. Reason : If the net external force is zero, a body at rest continues to remain at rest and a body in motion continues to move with a uniform velocity.

A positive point charge is placed in an external electric field. When we release the point charge in a state of rest then electric force acting on it starts moving it. Will the point charge always follow the electric lines of force?

A particle can move along a straight line. It is at rest when a force (F) starts acting on it directed along the line. Work done by the force on the particle changes with time(t) according to the graph shown in the fig. Can you say that the force acting on the particle remains constant with time?
