Question

Determine the force between two protons placed 1μm apart.
Options
A 2.3×10⁻¹³ N, attraction
B 2.3×10⁻¹³ N, repulsion
Correct Answer
C 2.3×10⁻¹⁶ N, attraction
D 2.3×10⁻¹⁶ N, repulsion
Correct Answer

Option B is the correct answer.

Detailed Explanation

F = kq²/r² = (9×10⁹)(1.6×10⁻¹⁹)² / (10⁻⁶)² = 2.3×10⁻¹³ N. Since both are positive, they repel

Hint

Like charges repel; use the charge of a proton.
