When two bodies collide elastically, the force of interaction between them is

When two bodies collide elastic, then:

Comprehension # 2 When two bodies collide normally they exert equal and opposite impulses on each other. Impulse = change in linear momentum. Coefficient of restitution between two bodies is given by :- e = |"Relative velocity of separation"|/|"Relative velocity of approach"| = 1 , for elastic collision Two bodies collide as shown in figure. During collision they exert impulse of magnitude J on each other. If the collision is elastic, the value of J is ............. N-s :-
