Estimate what was the initial speed of the alpha particle

Reference no: EM13564170

An alpha particle (charge +2e, mass 6.64x10^-27) moves head onat a fixed gold nucleus (charge +79e). If the distance of closestapproach is 2.0x10^-10m, what was the initial speed of the alpha particle? (an alpha particle is just a helium nucleus emitted inone type of nuclear decay).
