In case of earth potential
WebIn the case of the Earth-ball system, the force of gravity between the two depends only on the distance separating them. The work done in separating them farther, or in raising the … WebNov 14, 2024 · In case of gravitational potential energy, the potential energy is a shared property of both the body and the earth. The value of potential energy increases if the earth stays fixed and body moves upward, away from earth; it also increases if the body stays fixed and the earth is moved away from it.

WebThe gain of potential energy as it moves from A to B to C is consistent with the fact that the satellite moves further from the surface of the earth. As the satellite moves from C to D to E and back to A, it gains speed and loses height; subsequently there is a gain of kinetic energy and a loss of potential energy. WebResults Away from the Equator. At the poles, a c → 0 a c → 0 and F s = m g F s = m g, just as is the case without rotation.At any other latitude λ λ, the situation is more …
WebThe gravitational field inside earth is given by, E= R 3GM ex, where x is the distance of the object from center. As the object moves to center x=0 and therefore, E=0 . The assertion is therefore correct. We know that E= mF= [M][MLT −2]=[LT −2] The reason is also correct. But the reason is not the correct explanation for assertion.
