Here is the solution for the experiment "Determining the Earth's Gravitational Field Strength Using a Simple Pulley System", using assumed values as requested: Diagram [scale=1.0] % Clamp stand [thick] (0,0) -- (0,5); [thick] (-1,5) -- (1,5); [thick] (0,0) -- (2,0); at (0.5,5.3) Clamp; at (1,0.3) Stand; % Pulley [thick] (0,4.5) circle (0.5); [thick] (0,4.5) -- (0,5); at (0.8,4.5) Pulley; % String [thick] (0,4) -- (-2,4); [thick] (0,4) -- (2,4); % Mass m1 [thick] (-2,4) -- (-2,3); [thick, fill=gray!50] (-2,3) rectangle (-2.5,2.5); at (-2.25,2.2) m_1; % Mass m2 [thick] (2,4) -- (2,1); [thick, fill=gray!50] (2,1) rectangle (2.5,0.5); at (2.25,0.2) m_2; % Metre Rule [thick] (2.8,0) -- (2.8,4); in 0,1,2,3,4 (2.8,) -- (2.9,) node[right] ; at (3.2,2) Metre Rule (m); % Height h [<->] (2.6,1) -- (2.6,4) node[left, midway] h; % Stopwatch [thick] (-3,0.5) rectangle (-2,1.5); at (-2.5,1) Stopwatch; Procedure 1. Set up the apparatus as shown in the diagram. Ensure the pulley is frictionless and the string is light and inextensible. 2. Measure the masses of the two mass holders, m_1 and m_2, using an electronic balance. Adjust them so that m_1 > m_2. 3. Attach m_1 and m_2 to the ends of the string, passing the string over the pulley. 4. Adjust the position of m_1 to a suitable initial height (h) above the ground, using the metre rule. 5. Release the system from rest and simultaneously start the stopwatch. 6. Stop the stopwatch when m_1 hits the ground. Record the time t. 7. Repeat steps 4-6 for the same height h at least three times to obtain an average time. 8. Vary the height h (e.g., 0.2 m, 0.3 m, 0.4 m, 0.5 m, 0.6 m) and repeat steps 5-7 for each height. 9. For each height, calculate the average time t and then t^2. Observations/Results Assumed mass m_1 = 0.55 kg Assumed mass m_2 = 0.45 kg Total mass M = m_1 + m_2 = 0.55 kg + 0.45 kg = 1.0 kg Difference in mass m = m_1 - m_2 = 0.55 kg - 0.45 kg = 0.1 kg | Height h (m) | Time t_1 (s) | Time t_2 (s) | Time t_3 (s) | Average Time t (s) | t^2 (s^2) | | :------------- | :------------- | :------------- | :------------- | :------------------- | :------------ | | 0.2 | 0.64 | 0.63 | 0.64 | 0.64 | 0.41 | | 0.3 | 0.78 | 0.79 | 0.78 | 0.78 | 0.61 | | 0.4 | 0.90 | 0.91 | 0.90 | 0.90 | 0.81 | | 0.5 | 1.01 | 1.
