#6 The Sun produces energy by fusing hydrogen nuclei (protons) together to make helium. But protons are positively charged, so as they approach each other they initially feel a strong repulsive force. Which fundamental force would this be? Explain your reasoning.

Part III: The Inner Workings of the Sun
Now let's consider the effect that each of the four fundamental forces has on the inner workings
of our Sun:
#6 The Sun produces energy by fusing hydrogen nuclei (protons) together to make helium.
But protons are positively charged, so as they approach each other they initially feel a
strong repulsive force. Which fundamental force would this be? Explain your reasoning.
#7 In order for fusion to occur, protons must be moving very fast so they can get very close
together before the repulsive force of Question #3 can separate them. Fortunately, the
very high pressure and temperature in the core of the Sun are exactly what's needed to
get them moving that quickly. Which of the four fundamental forces compresses the
cores of very massive objects like the Sun? Explain your reasoning.
