AIPMT PRELIMS 2002 Physics Kinetic Energy MCQ Question
Type: MCQ-numerical-Medium-Class 11
If kinetic energy of a body is increased by 300% than percentage change in momentum will be
A
100%
B
150%
C
265%
D
73.2%
Correct Answer
Option A
Detailed Explanation
If KE increases by 300%, it becomes 4 times. KE = 0.5mv², so v² becomes 4 times. Thus, v becomes 2 times, and momentum p = mv becomes 2 times, i.e., a 100% increase.
