I need to find the length, weight of the bob and angle to make the pendulum a complete revolution. Kindly help me.
The formula for finding the length of the bob is L = gT^{2} / (4π^{2}sin^{2}θ), where L is the length of the bob, g is the acceleration due to gravity, T is the period of oscillation, and θ is the angle of displacement.
The weight of the bob can be measured using a scale or balance. Place the bob on the scale and record the weight displayed. Make sure to subtract the weight of any container or support used to hold the bob.
The units for the length of the bob are typically in meters (m) or centimeters (cm), depending on the scale of the experiment. The weight of the bob is usually measured in kilograms (kg) or grams (g).
The angle of displacement can be determined using a protractor. Place the protractor at the point of equilibrium (where the bob hangs straight down) and measure the angle between the string and the vertical line. This will give you the angle of displacement, θ.
Finding the length, weight, and angle of the bob is important in order to accurately calculate the period of oscillation for a pendulum. These values are used in the formula for period, and any errors in measurement can result in inaccurate results. Additionally, knowing these values can help in understanding the physics behind pendulum motion and its applications in various fields such as engineering and astronomy.
