Question

PLEASE HELP!!

The centers of two 15.0-kilogram spheres are separated by 3.00 meters. What is the magnitude of the gravitational force that one sphere exerts on the other?
A
1.11 × 10-10 N

B
3.34 × 10-10 N

C
1.67 × 10-9 N

D
5.00 × 10-9 N

Answer 1

C 1.67 × 10-9 N

Step-by-step explanation:

The magnitude of the gravitational force between two objects is given by:

`F=G(m_1 m_2)/(r^2)`

where

G is the gravitational constant

m1 ,m2 are the masses of the two objects

r is their separation

In this problem, we have:

`m_1 = m_2 = 15.0 kg`

r = 3.00 m

Substituting into the equation, we find

`F=(6.67\cdot 10^(-11)) ((15)(15))/(3.00^2)=1.67\cdot 10^(-9) N`
