The area of hole (1) is A_(1) and of hole (2) is A_(2) . The velocity of efflux and range of liquid is v_(1), v_(2) and x_(1), x_(2) for holes (1) and (2) respectively. The time taken by liquid, jet to reach the ground from holes (1) and (2) are t_(1) and t_(2) respectively. Cross section of tank is very very large compared to size of holes. {:(,"Column-I",,"Column-II"),((A),v_(1):v_(2),(p),2 : 1),((B),x_(1) : x_(2),(q),1 : 2),((C),t_(1) : t_(2),(r),1 : 1),((D),"if"A_(1) : A_(2) = 2 : 1",then"v_(1) : v_(2) =,(s),4 : 1):}
