A cannot ball is fired with a velocity 200m / sec at an angle of 60° with the horizontal. At the highest point of its flight it explodes into 3 equal fragments, one going vertically upwards with a velocity 100 m / sec , the second one falling vertically downwards with a velocity 100 m / sec . The third fragment will be moving with a velocity
A. 100m/s in the horizontal direction
B. 300 m/s in the horizontal direction
C. 300 m/s in a direction making an angle of `60^(@)` with the horizontal
D. 200 m/s in a direction making an angle `60^(@)` with the horizontal
