Question

Match the following

List - I	List - II
a) Relative velocity of approach and separation are same	e) Interaction between bodies
b) Bodies stick together	f) Newton's III law
c) Force	g) Coefficient of restitution $=$ 1
d) Recoil of the gun	h) Coefficient of restitution $=$ 0
	i) Binding energy

• A. a - g ; b - h ; c - e ; d - f
• B. a - h ; b - g ; c - f ; d -e
• C. a - g ; b - e ; c - f ; d -h
• D. a - e ; b - f ; c - g ; d -i

Answer 1

The correct option is A a - g ; b - h ; c - e ; d - f

Relative velocity of approach and separation are same implies, Coefficient of restitution = 1
If bodies stick together then velocity of separation is zero henceCoefficient of restitution = 0
Force is the result of interaction of bodies.
Recoil of gun is based on equal and opposite reaction to any force i.e., newtons III law.
