What is the quark composition of a Proton?
Correct answer: A. Two up quarks and one down quark
- A. Two up quarks and one down quark
- B. Two up quarks and one strange quark
- C. One up quark and two strange quarks
- D. Two down quarks and one up quark
Explanation
Protons and Neutrons are made up of 3 quarks each. An up quark has charge +2/3 whereas a down quark has charge -2/3. Protons have charge +1therefore have 2 up quarks and one down quark: (2*2/3) + (1 * -1/3) = +1

About Nuclear Physics
Atomic nuclei contain protons and neutrons, with nuclear size, mass defect and binding energy describing their stability. The work covers alpha, beta and gamma decay, decay equations, half-life and decay rate, along with radiation safety and medical applications such as imaging, radiotherapy and tracers.
