    OBSERVATION most of the alfa particles move simply without getting deflected some of them get deflected at small angles surprisingly one out of every 12000 particles get deflected at the angle of 180 degree CONCLUSION most of the space in an atom is empty because most particles didn't get deflected all the positive charge is resides at the center of the atom because a small no. of particles get deflected at small angles the positive charge is very small in size as only 1 out of 12000 get deflected at 180 degree

    A force where two forces of equal size, act on a body, in opposing directions is known as a Balanced Force. In Balanced Force, a body continues to be in its position i.e. it may be continuously moving with the same speed and in the same direction or it may be still in its position.
    Example of Balanced Forces- Suppose you are pushing a wall and as expected, the wall does not move and neither do you. It means that you and the wall are exerting a balanced force on each other.

    A force where two forces acting in opposing directions on a body, are not equal in magnitude and in size, is known as an unbalanced force. In an unbalanced force, a body changes its position i.e. we can observe a moving object changing its direction, either increasing the speed or decreasing the speed and a body at rest starts to move and vice versa. Example of Unbalanced Forces- Practically anything that moves is a result of the exertion of unbalanced forces on it. If you kick a football and it moves from one place to another, it means that unbalanced forces are acting upon it.
