Question1

In an assembly operation a robot moves an object first straight upward and then also to the east, around an arc forming one-quarter of a circle of radius 4.80cm that lies in an east-west vertical plane. The robot then moves object upward and to the north, through one-quarter of a circle of radius 3.70cm that lies in a north-south vertical plane. Find out-

(a) The magnitude of total displacement of the object

(b) The angle total displacement makes with the vertical.

Question2

Drawing the plot of the binding energy per nucleon versus mass number. Classify the key features. What is the origin of these descriptions? Put your answer in terms of the semi-empirical mass formula and what you know about the properties of the nuclear force.
