The Large Magellanic Cloud is a small galaxy that orbits the Milky Way. It is currently orbiting the Milky Way at a distance of

pogonyaev

Answer: $2.0416(10)^{42}kg$

Explanation:

Approaching the orbit of the Large Magellanic Cloud around the Milky Way to a circular orbit, we can use the equation of velocity in the case of uniform circular motion:

$V=\sqrt{G\frac{M}{r}}$ (1)

Where:

$V=300km/s=3(10)^{5}m/s$ is the velocity of the Large Magellanic Cloud's orbit, which is assumed as constant.

$G$ is the Gravitational Constant and its value is $6.674(10)^{-11}\frac{m^{3}}{kgs^{2}}$

$M$ is the mass of the Milky Way

$r=160000ly=1.51376(10)^{21}m$ is the radius of the orbit, which is the distance from the center of the Milky Way to the Large Magellanic Cloud.

Now, if we want to know the estimated mass of the Milky Way, we have to find $M$ from (1):

$M=\frac{V^{2} r}{G}$ (2)

Substituting the known values:

$M=\frac{(3(10)^{5}m/s)^{2}(1.51376(10)^{21}m)}{6.674(10)^{-11}\frac{m^{3}}{kgs^{2}}}$ (3)

$M=\frac{1.362384(10)^{32}\frac{m^{3}}{s^{2}}}{6.674(10)^{-11}\frac{m^{3}}{kgs^{2}}}$

Finally:

$M=2.0416(10)^{42}kg$ >>>This is the estimated mass of the Milky Way
