A proton with kinetic energy `K`, strikes another proton at rest. If the collision is head-on, find the correct graph between `K` and the distance of closest approach, `r`.

What happens to the kinetic energy of the particle at the distance of closest approach?

A block of mass m moving with speed v_(0) strikes another particle of mass 2 m at rest. If collision is head - on and the coefficient of restitution e = 1//2 , then the loss in kinetic energy will be

Define the distance of closest approach. An alpha -particle of kinetic enegy 'K' is bombarded on a thin gold foil. The distance of the closest approach is 'r' . What will be the distance of closest approach for an alpha -particle of double the kinetic energy ?

Define the distance of closest approach. An alpha -particle of kinetic enegy 'K' is bombarded on a thin gold foil. The distance of the closest approach is 'r' . What will be the distance of closest approach for an alpha -particle of double the kinetic energy ?

(a) Define the distance of closest approach. A alpha -particle of kinetic energy K is bombarded on a thin gld foil. The distance of the closest approach is r_(a) . What will be the distance of closest approach for an alpha -particle of double the kinetic energy ? (b) Show that the radius of the orbit of an electron in hydrogen atoms varies as n^(2) , where n is the principal quantum number of the atom.
