The centripetal force of 45n is required to revolve a stone of mass 100gm along acircular path of radius 50cm find the constant speed of the stone?

Centripetal force F=(m*v^2)/R
m=mass
v=velocity
R= radius of the circle in which the mass is rotating
^ means 'to the power of'
Therefore v^2=(F*R)/m=45*.5/.1=225.Therefore v=15m/s
As force is in Newton(SI UNIT) therfore we convrt the radius in metre
and mass to kilogram...

But gravity is constant it may be sun or earth therefore planet shoud be revolve in circular orbit?
please re write this question as it is inchoherent.
Do planets revolve around the sun at the same speed?
A planet has an elliptical shaped orbit. It orbits with a constant angular speed, but a varying linear speed.
Do stars revolve around satellites?
No, stars revolve around the galactic center.
Are all planet revolve around the sun?
are all planet revolve around the sun
Does Neptune rotate or revolve faster?
Rotate,because it takes 164.79 years to revolve
Why planet revolve not attached to the star?
During the revolve two forces acts on it that it centripetal force and centrifugal force. when planet approaches near the star due to centrifugal force and get attracted due to centripetal force.As both forces act simultaneously .Hence planet revolve
What force keeps and object in orbit?
Gravity holds an object in a circular orbit.
Time required for earth to revolve around ifself?
24 hours

What are the difference in the way animals and planets move?
At first i want to congratulate for thinking different. Animals move by legs, muscle (snail), they crawl (reptiles), fly (birds). Planets they move (revolve) due the centripetal force between the earth and planet.
Why does moons orbit the planets?
because the planets' gravity pull them so that they do not go away and the moons revolve around them with a constant speed so they stay in their orbit
Do planets revolve around the sun at the same speed?
A planet has an elliptical shaped orbit. It orbits with a constant angular speed, but a varying linear speed.
Do planets move?
Yes, because of the gravity of the sun they are moved in a circular motion that goes at a certain speed depending on the distance of the planets and centripetal forces. All the planets in out solar system revolve around the sun, while rotating on it's axes.
Is the sun revolve?
yes it revolve
Is the force of an object doubled if the velocity of an object traveling in circluar motion is doubled holding the radius constant?
If we're going to have this discussion, we need to change the playing field a bit.There's no such thing as the "force of an object". The only force that it makessense to talk about in this situation is the force on the object. That's the forcethat makes the object travel in a circular path, and it's called the "centripetal" force.In order to make an object move in a circular path, a constant force has to act on it,always directed toward the center of the circle. The force could be the tension ina yo-yo string, the friction between the race car and the track, or the gravitationalattraction between a body in a circular orbit and a big mass at the center.If the radius of the path remains constant but you want the object to revolve around ittwice as fast, then it needs 22 = 4 times as much centripetal force to keep it on thecircle, otherwise it skids away to a larger radius.
When was Revolve created?
Revolve was created in 2009.
What do moons revolve around?
They revolve around planets.
