A projectile of mass

M

is fired so that the horizontal range is

4 \mathrm{~km}

. At the highest point the projectile explodes in two parts of masses

M / 4

and

3 M / 4

respectively and the heavier part starts falling down vertically with zero initial speed. The horizontal range (distance from point of firing) of the lighter part is :

Options

A $16 \mathrm{~km}$
B $1 \mathrm{~km}$
C $10 \mathrm{~km}$
D $2 \mathrm{~km}$

Correct answer

C. $10 \mathrm{~km}$
