<h2>
Mass of object in Earth is 1.37 kg</h2>
Explanation:
On planet B where the magnitude of the free-fall acceleration is 1.91g , the object weighs 25.74 N.
We have
Weight = Mass x Acceleration due to gravity
On planet B
25.74 = Mass x 1.91 g
25.74 = Mass x 1.91 x 9.81
Mass = 1.37 kg
Mass is constant for an object. It will not change with location.
Mass of object in Earth = Mass of object in Planet B
Mass of object in Earth = 1.37 kg
potential energy because it has the ability to do work
Explanation:
A rock resting high in a cliff is an example of potential energy because it has the ability to do work. This form of energy is called potential energy.
- Energy is defined as the ability to do work. To do work, force must applied using energy to move a body through a particular distance.
- A body at rest is not doing any work. This is the case with potential energy of the body on a high cliff.
- At the state of rest, it is not doing any work.
- The potential energy of this body expresses the ability of such body to do work.

Electric force depends on the charge and the strength of the electric field. The equation that relates the three:
F = Eq where q is the charge and E is the electric field strength.
It might be a or d not too sure though
