For statement of question 118, if the heights of the two images are `h_(1)` and `h_(2)` , respectively,then the height of the object (h) is

Two particles are projected vertically upwards from the surface of the earth with velocities upsilon_(1) = sqrt((2gR)/3) and upsilon_(2) = sqrt((4gR)/(3)) respectively. If the maximum heights attained by the two particles are h_(1) and h_(2) respectively, then calculate the ratio (h_1)/(h_2) .

Two particles are projected vertically upwards from the surface of the earth with velocities upsilon_(1) = sqrt((2gR)/3) and upsilon_(2) = sqrt((4gR)/(3)) respectively. If the maximum heights attained by the two particles are h_(1) and h_(2) respectively, then calculate the ratio (h_1)/(h_2) .

A solid sphere and a solid cylinder of same mass are rolled down on two inclined planes of heights h_(1) and h_(2) respectively. If at the bottom of the plane the two objects have same linear velocities, then the ratio of h_(1):h_(2) is

Time taken by an object falling from rest to cover the height of h_(1) and h_(2) is respectively t_(1) and t_(2) then the ratio of t_(1) to t_(2) is

Two objects of masses m_(1) and m_(2) fall from the heights h_(1) and h_(2) respectively. The ratio of the magntidue of their momenta when they hit the ground is

In a cylindrical vessel containing liquid of density rho there are two holes in the side walls at heights of h_(1) and h_(2) respectively such that the range of efflux at the bottom of the vessel is same. The height of a hole for which the range of efflux would be maximum, will be
