Question

The sun attracts all bodies on the earth. At midnight, when the sun is directly below, it pulls on a body in the same direction as the pull of the earth on that body ; at noon, when the sun is directly above, it pulls on a body in a direction opposite to the pull of the earth. Then will the weight of the body be greater at mid-night than at noon ?

Answer 1

No every body placed on earth is a satellites for sun

Hence there will be no relative motion

Answer 2

$\underline{\underline{\Huge\mathfrak{Answer-: }}}$

◆No, earth is a satellite of sun. Every body placed on earth is also the satellite of sun. Both the body and earth will have the same acceleration towards the sun. Hence, there will be no relative gravitational acceleration between the body and the earth. It means, a body placed on earth will not experience any gravitational effect due to sun. It will experience gravitational force of attraction due to the earth, which will be the weight of the body measured on the surface of earth, which will remain same for all 24hours .
