Properties of Matter question

2022 · 29 Jun · Shift 2 · Q63

JEE MainPhysicsProperties of MatterNumerical+4 / −1
A small spherical ball of radius 0.1 mm and density 104 kg m −-− 3 falls freely under gravity through a distance h before entering a tank of water. If, after entering the water the velocity of ball does not change and it continue to fall with same constant velocity inside water, then the value of h will be ‾\underline{\hspace{2cm}}​ m. (Given g = 10 ms −-− 2, viscosity of water = 1.0 ×\times× 10 −-− 5 N-sm −-− 2).
