Question

Which one of the following actions makes it easier to move your LPG cylinder from one place to another?

• A. Lifting the cylinder
  
• B. Rolling the cylinder
  
• C. Moving the cylinder on the floor by pushing
  
• D. Moving the cylinder on the floor by pulling
  

Answer 1

The correct option is B Rolling the cylinder


Sliding friction is more than rolling friction, and hence pushing and pulling the cylinder will be harder than rolling it on the floor.

Lifting the cylinder also requires a lot of effort.

So, rolling the cylinder to move it from one place to another will require the least effort.
