Here are the solutions to your questions: 6. To calculate the force F: Step 1: Identify the pivot and the forces acting on the meter rule. The meter rule is uniform and balanced at its center, so the pivot is at the 50 cm mark. A force of 100 N acts at the 20 cm mark. Its distance from the pivot is 50 cm - 20 cm = 30 cm. This creates an anticlockwise moment. An unknown force F acts at the 70 cm mark. Its distance from the pivot is 70 cm - 50 cm = 20 cm. This creates a clockwise moment. Step 2: Apply the principle of moments for equilibrium. For the rule to be in equilibrium, the sum of clockwise moments must equal the sum of anticlockwise moments about the pivot. Anticlockwise Moment = Clockwise Moment 100 N × 30 cm = F × 20 cm Step 3: Solve for F. 3000 N cm = F × 20 cm F = 3000 N cm20 cm F = 150 N 7. To locate the image position using a ray diagram for an object placed in front of a concave mirror between C and F: Draw a ray from the top of the object parallel to the principal axis. After reflection from the mirror, this ray passes through the focal point (F). Draw a second ray from the top of the object passing through the focal point (F). After reflection from the mirror, this ray travels parallel to the principal axis. The point where these two reflected rays intersect is the location of the top of the image. The image formed will be real, inverted, and magnified, located beyond the center of curvature (C)*. 3 done, 2 left today. You're making progress.
