Find the false statement

A wooden cylinder is floating on water in a beaker which is placed in a lift. When the lift is at rest, one third of the volume of the wooden cylinder is exposed above water. the lift now moves up with an acceleration g/2. The fraction of the volume exposed now is :

The ratio of the radius of a planet 'A' to that of planet 'B' is 'r'. The ratio of acceleration due to gravity on the planets is 'X'. The ratio of the escape velocities from the two planets is :

The value of universal gravitational constant $$'G'$$  was first experimentally determined by : 

The weight of an object in the coal mine, sea level, at the top of the mountain are $$ W_1 , W_2$$ &  $$W_3 $$ respectively, then :-

The motion of planets in the solar system is an example of the conservation of

Escape velocity on earth is $$11.2$$ km/s. What would be the escape velocity on planet whose mass is $$1000$$ times and radius is $$10$$ times that of earth :

A battery of weight $$60kg-wt$$ is bought from earth surface to a space station at height equal to $$R_e$$, the weight of battery at their.

The escape velocity from earth is $$ V_e $$ A body is projected with velocity $$ 2V_e $$ with what constant velocity will it move in the interplanetary scape:

Escape velocity is given by :
