Question

Find the force of gravity between a cubic meter of water (1000kg) and the Sun. The Sun's mass is 1.99 x10^30 kg and is 1.50 x10^11 m away.

A) 17.0 N
B) 5.90 N
C) 2.0 N
D) 47.20 N

Answer 1

F = 5.9 N

Step-by-step explanation:

Given that,

Mass of water, m₁ = 1000 kg

Mass of the Sun,
`m_2=1.99* 10^(30)\ kg`

Distance between two bodies,
`r=1.5* 10^(11)\ m`

We need to find the force of gravity between water and the Sun. The formula for the gravitational force between two bodies is given by :

`F=G(m_1m_2)/(r^2)\\\\F=6.67* 10^(-11)* (1000* 1.99* 10^(30))/((1.5* 10^(11))^2)\\\\F=5.89\ N`

or

F = 5.9 N

Hence, the correct option is (b).
