Physics: Post your doubts here!
ii) Similarly, electric potential energy = kQ1Q2/R Q1 = charge of gold nucleus = 79 * 1.6 * 10^-19 C Q2 = charge on α nucleus = 2 * 1.6 * 10^-19 C energy = [79 * 2 * (1.6 * 10^-19)^2] / (4 * π * 8.85 * 10^-12 * 9.6 *10^-15) energy = 3.79 * 10^-12 J Hope u gt it!! :D -
Physics: Post your doubts here!
2 a i) Gravitational potential energy = gravitational potential * mass ---> gravitational potential = GM/R. So, Gravitational potential energy = GM1M2/R M1 = mass of the gold nucleus = (197 * 1.66 * 10^-27) kg M2 = mass of the α nucleus = (4 * 1.66 * 10^-27) kg... -
