Answer: The locus of points made by a pendulum of length 15 cm when it sweeps through an angle of 35⁰ is an arc of a circle.
A pendulum is a weight suspended from a pivot so that it can swing freely. As the pendulum swings, the weight moves along a circular arc. The center of this circular arc is the point of suspension, and the radius of the circle is the length of the pendulum.
When a pendulum swings through a small angle, the arc of the circle it sweeps through is approximately a straight line. However, when the pendulum swings through a larger angle, the arc it sweeps through is more pronounced, and the curvature of the arc becomes more noticeable.
In this case, the pendulum has a length of 15 cm and swings through an angle of 35⁰. The locus of points made by the pendulum is an arc of a circle with a radius of 15 cm and a central angle of 35⁰. The endpoints of the arc are the points where the pendulum is at its highest and lowest points, and the center of the arc is the point of suspension.
