Question

At noon, the sun and the earth pull the objects on the earth's surface in opposite directions. At midnight, the sun and the earth pull these objects in same direction. Is the weight of an object, as measured by a spring balance on the earth's surface, more at midnight as compared to its weight at noon?

Answer 1

Of course, the weight of an object measured by a spring balance at night is more at midnight when compared to that at noon.  

Explanation:

• This change in weight is sinusoidal and the value shall be very small which is not negligible.  
• All the objects in the celestial body have this pulling effect due to their mass and gravity.  
• Even moon has an effect in changing the weight of an object as the pulling effect of moon’s gravitational force plays a role in tidal effect in sea.

Answer 2

$\underline\red{\:\textsf{Explanation}}$

As you know, the gravitational pull of the Sun drops off as you go farther away from it. Then shouldn't that mean you should weigh differently at noon and midnight? The answer is actually no; at noon, it's true that you are pulled toward the Sun and off the Earth, but the Earth is pulled toward the Sun as well.
