Question

D 1,0 Q16 A projectile, following the usual parabolic trajectory , explodes into fragments midway in air. The centre of mass of fragments will follow A Horizontal rectilinear path B Same parabolic path C Vertical rectilinear path D Any parabolic path​

Answer 1

Explanation:

Physics formulas for Class 11 is one of the best tools to prepare physics for Class 11 examination and various competitive examinations. Physics is a subject that deals with the natural world and the properties of energy and matter, etc. The 11th standard is filled with advanced level physics questions and numerical which students should understand in order to score good marks in their board exam. The physics formulas for Class 11 will not only help students to excel in their examination but also prepare them for various medical and engineering entrance exams.

Physics is filled with complex formulas and students must understand the concepts behind the formulas to excel in the subject. The physics formulas are given in proper order so that students can learn the subject step by step. Students are advised to learn the formulas thoroughly to score good marks in important physics topics like thermodynamics, electric current, laws of motion, optics, energy conversion, etc.

Answer 2

Answer:

Option (B) Same parabolic path

Explanation:

While the projectile is in the midway in the air, the only external force acting on it is that of gravity. Now, assuming for a while that the projectile do not explodes then its obvious that it would have followed a parabolic path.

Now, we know that the projectile exploded due to changes in its internal forces. We also know that centre of mass of a projectile can be change only by the external forces. Its internal forces has nothing to do with change in position/path of centre of mass.

Therefore, the projectile even after explosion will follow the same parabolic path.
