Question

A 1,650-kg car stands on a square platform, and a 75-kg man simply stands on another square platform. These platforms are in fact two caps of a large oil-filled container. What must be the relation between the areas of the two platforms (that under the car and that under the man), for the man to be able to barely lift the car just by standing on his platform, without applying additional forces with his muscles?

-The area of the car's platform must be approximately 22 times that of the man's platform.

-The area of the man's platform must be exactly equal to that of the car's platform.

-The area of the man's platform must be approximately 22 times that of the car's platform.
