Question

A scientist uses an accelerator and high energy electrons to study the particles inside the protons of a helium atom. What particles is the scientist studying? A. the He neutrons B. the He nucleus C.the He electrons D.the He quarks

Answer 1

Atoms are made up of protons, neutrons and orbiting electrons. Scientific discoveries found out that there are even smaller parts of these sub particles called quarks, anti-quarks and gluons. A proton is made up of three quarks (two up quarks and a down quark). answer is D.

Answer 2

Answer : Option D) The He quarks

Explanation :

The scientist uses an accelerator and high energy electrons to study the particles inside the protons of a helium atom, the particles under study are quarks.

Quarks are the elementary and fundamental part of matter. In Helium nucleus when the high energy is bombarded to study the particles inside the proton it is obvious that the scientist is studying the quarks inside the proton. In a proton there are two up quarks and one down quark present.
