Question

A uniform, spherical, 1900.0 kg shell has a radius of 5.00 m. Find the gravitational force this shell exerts on a 1.80 kg point mass placed at the distance 5.01 m from the center of the shell.

Answer 1

`F=9.09* 10^(-9) N`

Step-by-step explanation:

We are given that

Mass of spherical shell,
`m_1`=1900 kg

Mass=
`m_2=1.80 kg`

Radius of shell=r=5 m

Distance between two masses=r=5.01 m

Because distance measure from center .

Gravitational force

`F=G(m_1m_2)/(r^2)`

`G=6.67* 10^(-11) Nm^2/kg^2`

Using the formula

`F=6.67* 10^(-11)* (1900* 1.80)/((5.01)^2)`

`F=9.09* 10^(-9) N`

Hence,the gravitational force =
`F=9.09* 10^(-9) N`
