Two protons are separated by a distance R. What will be the speed of each proton when they reach infinity under their mutual repulsion?

Two protons are placed 1 Å apart. If they are released, what will be the kinetic energy of each proton when they are at large separation :-

(a) Two protons are placed at separation d on a smooth surface. Find the speed of each proton when separation between them is doubled. (b) An alpha -particle and a proton are placed at a separation d on a smooth surface.Find the speed of each when separation between them becomes infinite. ( m : mass of proton , e : charge of proton.)

Two balls of radius r each are placed at a distance R and released . The speed of each ball when they collide

Two balls of radius r each are placed at a distance R and released . The speed of each ball when they collide

the coulombian force acting between two protons separated by a distance r is F, what would be the force acting between two alpha particles seperated by a distance 2r ?

An electron and a proton are separated by a large distance and the electron approaches the proton with a kinetic energy of 2 eV. If the electron is captured by the proton to form a hydrogen atom in the ground state, what wavelength photon would be given off?
