| A projectile is fixed at an angle and was following a parabolic path. Suddenly it explodes into fragments. Choose the correct option regarding this situation. |
 |
A) The concept of the CM is applicable to rigid bodies as well as system of particles
B) The path of the CM of the system of particles will remain parabolic after the explosion
C) Both [a] and [b] are correct
D) Both [a] and [b] are incorrect
Correct Answer: C
Solution :
In this given situation, projectile could be considered as rigid body before explosion, after explosion its fragments are considered as system of particles. The CM concept is applicable to both, we can say as the explosion is due to internal forces, so the motion of CM after explosion is due to internal forces, so the motion of CM after explosion will follow the same parabolic path as it would have followed if there was no explosion.
