In Rutherford's experiment including the deflection of alpha particles by atomic nuclei, the fact that some of the alpha particles bombarding the thin gold foil were back-scattered, led to.
It was concluded that
Ans- Most of the mass of a gold atom is in its nucleus

two insulated charged copper spheres A and B of identical size have charge q and -3q respectably .when they are brought in contact with each other and then separated,what are the n
It is the difference among potential at two points of a conductor. Please note that by potential(at a point A) ,we actually mean potential difference among point A and another
Factors on which Resistance Depends: Resistance of the conductor depends on the following factors. Nature of the conductor. Length of the conductor. Area of cross sect
