Question
Two bodies of mass m and 4m are moving with equal kinetic energy. Then the ratio oftheir liner momentum will be:
Options
A.1 : 1
B.2 : 1
C.4 : 1
D.1 : 2
Solution
Relation between momentum and enegrg is
E =
= 1
⇒ p1 : p2 = 1 : 2
E =
= 1 ⇒ p1 : p2 = 1 : 2Create a free account to view solution
