Question

Q.29 An alpha particle of charge 3.2×10-19 cm/sec and mass 6.8×10^-27Kg is initially moving at speed 107 when it is at far distance from another fixed point charge 112×10-19C. Find the distance of closest approach​

Answer 1

Answer:

An alpha particle is identical to a helium atom that has been stripped of its two electrons; thus, an alpha particle contains two protons and two neutrons. Because an alpha particle has no electrons to balance the positive charge of the two protons, it has a charge of +2 and can be represented as He2+.
