A ring of mass 0.3kg and radius 0.1m and a solid cylinder of mass 0.4kg and of the same radius are given the same kinetic energy and released simultaneously on a flat horizontal surface such that they begin to roll as soon as released towards a wall which is at the same distance from the ring and the cylinder. The rolling fric tion in both cases is negligible. Then
1. the cylinder will reach the wall first
2. both will reach the wall simultaneously
3. the ring will reach the wall first
4. none will reach the wall
Option 2 – both will reach the wall simultaneously
The mass of a balloon with its contents is 1.5kg, it is descending with an acceleration equal to half that of acceleration due to gravity. If it is to go up with same acceleration keeping the volume same, it should be decreased by

2. 0.5kg
3. 1kg
4. 2kg
Option 3 – 1kg
