Teaching HTET PGT Level 3 - 2024 Mock Test Physics Gravitation Acceleration due to gravity of the earth
An object of mass 5 kg is thrown vertically upwards from the ground. The air resistance produces a constant retarding force of 10 N throughout the motion. The ratio of time of ascent to the time of descent will be equal to [Use g = 10 ms–2].
