<u>Answer:</u>

The effort is required to raise bucket of water from the bottom of a well is 200N

<u>Explanation : </u>

Radius of the larger wheel = 40cm

Radius of the axle = 10cm

Mass of the bucket of water= 50N

Now,

According to the gravitational formula

          Force  = mgR

Due to constant acceleration g has no value  

M is the mass of the bucket of water

R is the radius of the larger wheel/radius of the axle

= \frac{40cm}{10cm}

=4cm

Substituting the values in mgR

= 50\times4

=200N

Hence, 200N of force is required to raise it.
