Q1. An object 0.600 cm tall is placed 16.5 cm to the left of the vertex of a concave spherical curvature of 22.0 cm.

a). Sketch a principle ray diagram showing the formation of the image.

b). compute the position, size, orientation (erect or inverted), and nature (real or virtual) of the image.

Q2. A one meter chain that weighs one Newton sits on a flat horizontal table which is one meter from the floor. The coefficient of friction between the chain and table is 0.15. How much of the chain can dangle off the table until chain pulls itself onto the floor? If it starts to fall from this position of "maximum dangle", how fast is chain moving when it first hits the floor.
