Exercise 1

Suppose two alpha particles were held together so they were just touching.

1-Estimate the electrostatic repulsive force each would exert on the other. (answer in 2 sig figures)

2-What would be the acceleration of an alpha particle subjected to this force? answer in m/s²

Exercise 2

If an alpha particle were released from rest near the surface of a100257Fm nucleus, what would its kinetic energy be when far away? (answer in 2 sig figures in MeV)

Exercise 3

1-Determine the average binding energy of a nucleon in1123Na .Express your answer using four significant figures in MeV/ nucleon.
