Two alpha particles (heliumnuclei), each consisting of two protons and two neutr

Question

Two alpha particles (heliumnuclei), each consisting of two protons and two neutrons, have anelectrical potential energy of 6.35 × 1019 J. Given: ke = 8.98755 × 109Nm2/C2 , qp =1.6021 × 1019 C, and g = 9.8m/s2 . What is the distance between these particles at this time?Answer in units of m.

Explanation / Answer

   6.35 *10-19   =   8.98755 *109 * 2 * 1.6021 * 10-19 * 2 * 1.6021 *10-19 / r    distance   r   =   4 * 2.30686 * 10-28   / 6.35 *10-19                       = 1.4531* 10 ^ -9 m                       = 1.4531* 10 ^ -9 m
