A stationary body of mass m explodes into three parts having masses in the ratio 1 : 3 : 3. The two fractions with equal masses move at right angles to each other with a velocity of \[1.5\text{ }m{{s}^{-1}}\]Then the velocity of the third body is:

A)  \[4.5\sqrt{2}m{{s}^{-1}}\]                          

B)  \[5\,m{{s}^{-1}}\]          

C)         \[5\sqrt{32}m{{s}^{-1}}\]     

D)         \[1.5\,m{{s}^{-1}}\]

E)  \[1\,m{{s}^{-1}}\]
