Question

A woman weighs $500N$ on earth. With how much force is her body pulling up on the earth?

• A. $0$ Newtons
• B. Between $0$ and $500$ Newtons
• C. $500$ Newtons
• D. Between $500$ and $1000$ Newtons
• E. Greater than $1000$ Newtons

Answer 1

The correct option is C $500$ Newtons

From Newton's third law, the woman exerts an equal and opposite force on earth as compared to that which earth exerts on earth.
Hence even the woman exerts $500N$ of force on earth towards her.
