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

Answer:

$F=9.09\times 10^{-9} N$

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

$F=G\frac{m_1m_2}{r^2}$

$G=6.67\times 10^{-11} Nm^2/kg^2$

Using the formula

$F=6.67\times 10^{-11}\times \frac{1900\times 1.80}{(5.01)^2}$

$F=9.09\times 10^{-9} N$

Hence,the gravitational force =$F=9.09\times 10^{-9} N$
