I'm not sure what you mean by 'force is needed'. Needed to do what?
The Newton is defined as the force required to accelerate a mass of 1 kg at a rate of 1 m/sec2. Clearly if you double the mass and keep the acceleration the same, the force required is also doubled.
The mass has no effect on the forces. The force applied to the object is decided
by the person doing the pushing, not by the mass of what he's pushing on. You
can easily push on a battleship and a bicycle with the same force if you want to.
If the object was stationery before any forces were applied it will remain stationery, and if it was moving it will remain moving but at a constant speed. There is no resultant force so the object experiences no acceleration.
If there are two or more unequal forces acting on an object then the object will be acting on the forces. ^_^
Newton's second law of motion provides an explanation for the behavior of objects when forces are applied to the objects. The law states that external forces cause objects to accelerate, and the amount ofaccelerationis directly proportional to the net force and inversely proportional to the mass of the object.
Because NOT all forces are equal and opposite. By Newton's Third Law, if object A attracts object B, then object B also attracts object A - with an equal but opposite force. But those forces act on DIFFERENT objects! The forces on object A, and on object B, may be unbalanced!Because NOT all forces are equal and opposite.

When balanced forces are applied to a moving object, the object likely slow and eventually stop. How quickly that occurs depends on the amount of force.
If the [group of] forces on an object is unbalanced, the object accelerates.
None. There is no effect on a stationary object.
The falling object
when different forces are applied to two different objects of same s the force with the most energy will push the other object
Balanced forces applied on both sides of an object cause it to be still. Unbalanced forces will cause the object to move away from the strongest force.
Then the effect is as if there are no forces on it at all, and it moves in a straight line with constant speed.
If they are balanced and equal they have no overall effect on the acceleration of an object.
when the forces are balanced ,means a net external force is applied the object continues to be in the same state of rest or of motion
"Balanced forces" means a set of forces that add up to zero.This group of forces acting on a single object have no effect on its motion, because they add up to zero,and their effect is equivalent to zero force on the object.
If the object was stationery before any forces were applied it will remain stationery, and if it was moving it will remain moving but at a constant speed. There is no resultant force so the object experiences no acceleration.
An internal force is a force acted upon by an object to force another object's movement internally. An external force is a force exerted on an object based on the objects position and force applied on the object which causes the opposite forces change in motion.
When the forces acting on an object are balanced, they cancel each other out and the result is no change in its motion.Balanced forces have no effect on motion. Unbalanced forces cause acceleration.
