A shell is projected at an angle with horizontal. It explodes alongits flight into fragments. How does the centre of mass of fragments behave?

Options

A. Straight line
B. Parabolic path
C. Hyperbolic path
D. Elliptical path

Answer

B

Explanation

The projected shell, before explosion, moves along a parabolic path. The explosion is under the effect of internal forces only. There is no external force applied to the system. Hence, the centre of mass of fragments continue to lie along the parabolic path.
