Question

A Gravitational force between two masses at a distance ${}^{\prime }{d}^{\prime }$ apart is $6N.$ If these masses are taken to the moon and kept at same separation, then the force between them will be.

• A. $1N$
• B. $\frac{1}{6}N$
• C. $36N$
• D. $6N$

Answer 1

Answer: (D)

$6N$

Gravitational force between two objects is $\frac{G{m}_1{m}_2}{r^2}$.

Since at moon, the mass of the objects and the distance between them remain the same, and G is obviously a universal constant, the force between them remains the same.
