Question

A wooden raft has a density of 0.500x103
kg.m 3 and
dimensions of 3.05 m x 6.10 m x 0.305 m. How deep does

t sink into the water when unloaded? What is the maximum
number of 70 kg people can the raft carry before it sinks?

Answer 1

Explanation:

Answer:

The gravitational force will remain same.

The gravitational force between the objects after the space around them is filled with water will remain same as they are kept in air.

Explanation:

we know that ,

gravitational force between two objects is given by,   =

where   G = gravitational constant  ( G = 6.674×10^(−11)  )

are mass of two objects

and R = distance between them

It is clear that

" The gravitational force between two objects is independent of the medium in which the two masses are present "

gravitational force between two objects placed in air = F

The gravitational force between the objects after the space around them is filled with water = F

hence the gravitational force between two objects kept at a distance will remain same everywhere irrespective of the medium they are present.
