Marvin Martian is standing on planet Potatoine.

prisoha [69]

Answer:

W = 113.98 N

Explanation:

Given that,

Radius of Potatoine $R=6.4\times 10^6\ m$

Mass of Potatoine, $M=2\times 10^{24}\ kg$

Mass of Marvin, m = 35 kg

We need to find his weight on Potatoine. Weight of an object is given by :

W = mg

g is acceleration due to gravity, $g=\dfrac{GM}{R^2}$

So,

$W=\dfrac{GMm}{R^2}\\\\W=\dfrac{6.67\times 10^{-11}\times 35\times 2\times 10^{24}}{(6.4\times 10^6)^2}\\\\W=113.98\ N$

So, his weight on Potatoine is 113.98 N.

A satellite moves in a stable circular orbit with speed Vo at a distance R from the center of a planet. For this satellite to mo

slava [35]

Answer:

The new speed must be $\frac{V_0}{\sqrt{2}}$

Explanation:

In order for the satellite to be on a stable orbit around the planet, the gravitational attraction must be equal to the centripetal force that keeps the satellite in circular motion:

$G \frac{Mm}{R^2}= m\frac{V_0^2}{R}$

where G is the gravitational constant, M is the mass of the planet, m is the mass of the satellite, V0 the speed of the satellite at distance R from the center of the planet.

We can re-write V0, the initial satellite speed, by re-arranging the equation:

$V_0 = \sqrt{\frac{GM}{R}}$

Now, if we want the satellite to orbit at a distance of 2R, the new tangential speed must be:

$V' = \sqrt{\frac{GM}{2R}}=\frac{1}{\sqrt{2}} \sqrt{\frac{GM}{R}}= \frac{V_0}{\sqrt{2}}$

I would say D is the right answer.

If the object is in an electromagnetic field, then it's movement can be generalized by interactions between charges.
