    The maine drawback of Rutherford's model was that it could not explain the stability of an atom. According to him -ve charged electrons are revolving around the +be charged nucleus. But according to Maxwell's theory of radiation whenever a charged body revolves it emits radiation and loses energy. Thus in that case the atom would collapse and matter would cease to exist

    1- First law of motion - states that an object will continue to remain in its state of rest or in a uniform motion along a straight line or path unless an external force acts on it. 2- Second law of motion - states that the rate of change of momentum of an object is proportional to the applied external force and takes place in the direction in which external force acts. 3- Third law of motion - states that whenever one object exerts a force on other object, then the second object exerts an equal and opposite force on the first object.
