Question
The kinetic energy of a body becomes four times its initial value. The new linear momentum will be
Options
A.eight time of the initial value
B.four time of the initial value
C.twice of the initial value
D.remain as the initial value
Solution
The relation between kinetic energy and linear momentum is
E =
so E ∝ p2
If energy becomes four time then momentumwill become twice as p ∝ √E
E =
so E ∝ p2 If energy becomes four time then momentumwill become twice as p ∝ √E
