Mass of an object/person remains same, doesn't depend on gravity, so if his mass is 75 Kg somewhere, then, it would remain same everywhere. Only Weight of a person changes with gravity.
In short, Your Answer would be "Equal to 75 Kg"
Hope this helps!
Answer: Around 364 to 480
Answer:
a). The potential is highest at the center of the sphere
Explanation:
We k ow the potential of a non conducting charged sphre of radius R at a point r < R is given by
Therefore at the center of the sphere where r = 0
Now at the surface of the sphere where r = R
Now outside the sphere where r > R, the potential is
This gives the same result as the previous one.
As
Thus, the potential of the sphere is highest at the center.
