From a 10 m high building a ston 'A' is dropped, and simultaneously another identical stone 'B' is thrown horizontally with an initial speed of `5ms^(-1)`. Which one of the following statement is true?

A particle (A) is dropped from a height and another particles (B) is thrown into horizontal direction with speed of 5m/s sec from the same height. The correct statement is

A ball is thrown downwards with a speed of 20 m s^(-1) , from the top of a building 150 m high and simultaneously another ball is thrown vertically upwards with a speed of 30 m s^(-1) from the foot to the building . Find the time after which both the balls will meet. (g=10 m s^(-2)) .

A ball is thrown downwards with a speed of 20 ms^(–1) from top of a building 150m high and simultaneously another ball is thrown vertically upwards with a speed of 30 ms^(–1) from the foot of the building. Find the time after which both the balls will meet - (g = 10 ms^(–2))
