Explanation:

Yes, if force is acting on a body work done can be zero. When an object is at rest and no external force except gravity is acting on it in this case the work that would be zero as the force acting on it is perpendicular.

For example,

When an object is at rest and no external force except gravity is acting on it in this case the work that would be zero as the force acting on it is perpendicular. Therefore the displacement is zero and if displacement is zero work done would be zero.

We know that,

The work done

W=fs

Suppose that displacement is zero then,

W=f×0

W=0

The work done is zero.

The gravitational field on Saturn is 10.4 times its value on Earth.
nalin [4]

The weight of 100 kg mass on Saturn is 10,192 N.

The weight of 7.0 kg mass on Pluto is 2.01 N.

The given parameters;

  • <em>acceleration due to gravity, = 10.4g</em>
  • <em>mass of the Saturn, m = 100 kg</em>
  • <em>acceleration due to gravity on mercury, = 3.59 m/s²</em>

The weight of 100 kg mass on Saturn is calculated as follows;

W = mg

W = 100 x 10.4 x 9.8

W = 10,192 N

The weight of 7.0 kg mass on Pluto is calculated as follows;

W = 7 x 0.08 x 3.59

W = 2.01 N
