How to Calculate the Force of Gravity When Mass is Reduced

What kind of force will a person feel if his mass is reduced by 2/5?

a. 375 N
b. 250 N
c. 625 N
d. 750 N

Final Answer:

If the mass of a person is reduced by 2/5, the force of gravity acting on them will also be reduced by the same factor. In this case, the person feels an attractive force of 625 N from Earth. If their mass is reduced by 2/5, the force they will feel is 250 N.

Gravity is the force that attracts objects towards the center of the Earth. The force of gravity is determined by the mass of the object. So, if the mass of a person is reduced by 2/5, the force of gravity acting on them will also be reduced by the same factor.

In this case, the person feels an attractive force of 625 N from Earth. If their mass is reduced by 2/5, the force they will feel will also be reduced by 2/5. Therefore, the force they will feel is (2/5) * 625 N = 250 N.

So, the correct answer is b. 250 N.
