Question 1

The rest-energy of the Z⁰ boson is 96 GeV. Using this information, find the maximum length of time a virtual Z⁰ can exist, in accordance with the uncertainty principle

. (1 eV = 1.6 × 10⁻¹⁹ J.)

◦

7.5 × 10⁻³⁰ s

◦

2.4 × 10⁻²⁴ s

◦

1.9 × 10⁻²¹ s

◦

6.3 × 10⁻⁵ s

Question 2

The strong nuclear interaction has a range of approximately 0.70 × 10⁻¹⁵ m. It is thought that an elementary particle is exchanged between the protons and neutrons, leading to an attractive force. Utilize the uncertainty principle

to estimate the mass of the elementary particle if it moves at nearly the speed of light.
