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
A resistor is a two-terminal electrical or electronic component that resists an electric current by producing a voltage drop between its terminals in the accordance with ohm’s law.
