A juggler keeps on moving four balls in air throwing the balls after regular intervals. When one ball leaves his hand (speed \( =20 \mathrm{~m} \mathrm{~s}^{-1} \) ), the position of other balls (height in meter) will be (take \( g=10 \mathrm{~m} \mathrm{~s}^{-2} \) )
(1) \( 10,20,10 \)
(2) \( 15,20,15 \)
(3) \( 5,15,20 \)
(4) \( 5,10,20 \)
