the answer is the first one because neutrons and protons are in the middle of an atom. plz give me brainliest
Answer:
6.58×10⁻¹⁸ J
Explanation:
Applying
E = kq²/r.................. Equation 1
Where E = potential energy, q = charge on each electron, r = distance between the electron, k = coulomb's constant.
From the question,
Given: r = 3.5×10⁻¹¹ m,
Constant: q = 1.6×10⁻¹⁹ C, k = 8.99×10⁹ Nm²/C²
Substitute these values into equation 1
E = (1.6×10⁻¹⁹)²(8.99×10⁹)/(3.5×10⁻¹¹)
E = 6.58×10⁻¹⁸ J
Answer:
The strength of gravity decreases.
An example of that would be if you were in space; you float around because there's no gravity.
They believe the distortions happened when two galaxies collided.
Hope This Helps :)
