A ball is thrown vertically upwards with a speed of `10 m//s` from the top of a tower 200 m height and another is thrown vertically downwards with the same speed simultaneously. The time difference between them on reaching the ground is `(g=10 m//s^(2))`

A ball is thrown vertically upwards with a speed of 10 ms^-1 from the top of a tower 200 m high and another is throwtl .vertically downwards with the same speed simultaneously. The time difference between them in reaching the ground, in second, if g is taken as 10 ms^-2 , is
