Textbook Problem

A proton and an alpha particle (charge = 2e, mass = 6.64 × 10−27 kg) are initially at rest, separated by 4.00 × 10−15 m. (a) If they are both released simultaneously, explain why you can’t find their velocities at infinity using only conservation of energy. (b) What other conservation law can be applied in this case? (c) Find the speeds of the proton and alpha particle, respectively, at infinity.

(a)

To determine
Why the velocities of the proton and alpha particle can’t be determined.

Explanation

Mass of alpha particle is greater than that of proton. When the final speeds of the particles are obtained using the law of conservation o...

(b)

To determine
The conservation law to be applied.

(c)

To determine
The speeds of proton and alpha particle at infinity.
