Question

Shown below is a configuration of a circle and a rigid rod. The length of the rod PQ is equal to the circumference of the green circle. The rod tangentially revolves around the circle till point Q reaches point P. Which option represents the CORRECT tracing of point Q?

• A. A
• B. B
• C. C
• D. D

Hint:

In problems involving motion along a curve, understand the path traced by a point on the moving object and match it with the correct option.

Answer 1

The Correct Option is C

Step 1: The rod moves tangentially around the circle. Since the length of the rod is equal to the circumference of the circle, point Q will trace a specific curve as the rod moves.
Step 2: Visualize the motion of point Q and match it with the correct tracing shown in the options.
Step 3: Option (C) shows the correct tracing of point Q as the rod moves around the circle.
