Question

The weight of an object at the center of a planet of radius R is:

• A. $zero$
• B. $\frac{1}{R^2}timestheweightatsurface$
• C. $\frac{1}{R^2}timestheweightatsurface$
• D. $infinite$

Answer 1

The correct option is A $zero$

At the center of the planet, you experience zero net force since every mass particle is equally pulling on you in different directions that all cancel out. Thus, accelerationdue to planet is zero and making the weight 0.
