Question

A proton is fired from far away toward the nucleus of an iron atom. Iron is element number 26, and the diameter of the nucleus is 9.0 fm. (1 fm = 10^-15 m.) Assume the nucleus remains at rest. What initial speed does the proton need to just reach the surface of the nucleus?

Step 1

This can be calculated using the equation: \[ \frac{1}{2}mv^2 = \frac{k_e \cdot q_1 \cdot q_2}{r} \] where: m = mass of the proton = \(1.67 \times 10^{-27} kg\) v = initial speed of the proton \(k_e\) = Coulomb's constant = \(8.99 \times 10^9 Nm^2/C^2\) \(q_1\) Show more…
