A particle is projected with 200 , at an angle of 60 . At the highest point it explodes into three particles of equal masses. One goes vertically upward with velocity 100  the second particle goes vertically downward with the same velocity as the first. Then what is the velocity of the third particle?

a)

120  with 60  angle

b)

200  with 30  angle

c)

50  vertically upwards

d)

300  horizontally

Answer Key : (d) -

(d)

At the highest point momentum of particle before explosion

 horizontally

Now as three is no external force during explosion, hence

However, since velocities of two fragments, of masses  each, are 100  downward and  upward.
hence,  or

 m horizontally

 horizontally
