Question
If the kinetic energy of the body becomes four time of its initial of its value, then the the new momentum will
Options
A.become twice its initial value
B.remain constant
C.become four times its initial value
D.become three time its initial value
Solution
E = 
; E ∝ p2
⇒ 
retio of momentum = 1 : 2
; E ∝ p2 ⇒ retio of momentum = 1 : 2
