The gold foil experiment demonstrated that most of an atom is empty space with a very small positively charged nucleus in the middle. His result was that 99.995% Î±-particles were not deflected. This proved that atoms had an inner core that contained most of the mass of an atom and was positively charged. Comments

Calculate the time of one oscillation or the period (T) by dividing the total time by the number of oscillations you counted. Use your calculated (T) along with the exact length of the pendulum (L) in the above formula to find g.. This is your measured value for  g. . Repeat the above procedure for 3 more cases. Choose 3 other values for L between 125cm and 158cm and record them in the Table in rows 2, 3, and 4.
