Hello, here we have to solve the following problem.
00:02
In a distance solar system, a planet has a mass of 3 .75 times 10 power by 28 kilograms.
00:10
And it's orbiting its sun with a mass of 4 .94 times 10 power by 30 kilograms, with an orbital radius of 1 .94 times 10 power by 11 meters.
00:24
First, we have to calculate the net gravitational field strength midway, between the planet and the sun in the units of newton per kilogram.
00:37
So let's do this calculation.
00:39
Let's call this, yeah, let's call this strength as s, for example.
00:45
And this s is g times mass of the sun, divided by radius over 2, r over 2, which is squared.
01:00
Now we can proceed to the calculation part.
01:19
Now let's complete this calculation.
01:20
This field is 0 .051, 350 newton per kilogram.
01:33
So now in question 2, or in question b, we have to calculate the gravitational potential at the distance of 2 .26 times 10 power by 7 meters from the center of the planet which has a radius of point 55 times 10 power by 6 meters and with a mass of oh actually here this potential at this given radius at this given distance let's call it 5 1 is negative 5 .64 times 10 power by 7 joule per kilogram and we have to calculate the gravitational potential at the distance of d2 of 4 .3 times 10 power by 7 meters from the center of this planet...
