Question
How can an object move with zero acceleration (constant velocity) when the external force is acting on the object?
✓

Answer

It is possible when there is another force which acts exactly opposite to the external applied force. They both cancel each other and the resulting net force becomes zero, hence the object moves with zero acceleration.
