Hello everyone.
00:03
So in the question it is asked that which of the following statements concerning a planet orbiting around the sun is true.
00:11
Okay? so we have to state which of the following option is true.
00:17
Now, the centripetal force that is mv squared divided by r should be equal to the gravitational force.
00:30
G, mass of planet multiplied by mass of sun divided by r square okay so these force should be equal to keep the planet in its orbit okay now in the first option it is given to us that the gravitational force between the planet and the sun must be larger than the centipotal force needed to keep the planet in its orbit so clearly the statement is is true, we need both of the forces to be equal to keep the planet in its orbit.
01:09
So the first option is false.
01:15
Now the second option is given as the centripetal force that keeps the planet moving in a stable orbit is provided by the gravitational acceleration between the planet and the sun.
01:29
Now this is true.
01:31
Okay, centripetal force that is mb square by r is given by the gravitational force.
01:40
Okay, so this statement is true, okay? b statement is true...
