An alpha particle the nucleus of a helium atom with charge, Ask an Expert

Academics

An alpha particle (the nucleus of a helium atom, with charge +2 and a mass four times that of a proton) and an antiproton (which has the same mass as a proton but charge -) are released from rest a great distance apart. They are oppositely charged, so each accelerates toward the other.

Part A: What is the speed of the alpha particle when the particles are 1.6 nm apart?

Part B: What is the speed of the antiproton when the particles are 1.6 nm apart?
