A proton collides with a neutron (mass almost identical to the proton) to form a deutron. What will be the velocity of the deutron if it is formed from a proton moving with velocity ( 7.0 × 10^ 6 m s ) to the left and a neutron moving with velocity ( 4.0 × 10^ 6 m s ) to the right?(proton mass =1.67×10 -27 kg)
