Statement-1
In an elastic collision between two bodies, the relative speed of the bodies after collision is equal to the relative speed before the collision. because
Statement-2
In an elastic collision, the linear momentum of the system is conserved

Question

Accepted Answer

Correct answer: B. (d) According to Newton’s Law e = v_2− v_1 u_1− u_2 For elastic collision cofficient of restitution e = 1 so v_2− v_1 = u_1− u_2 Statement - 1 is correct Linear momentum is conserved in both elastic & non elastic collision but it’s not the explanation of statement -1 so it is not the correct explanation of the statement A.

$Statement-1 In an elastic collision between two bodies, the relative speed of the bodies after collision is equal to the relative speed before the collision. because Statement-2 In an elastic collision, the linear momentum of the system is conserved$
