Calculating Force for 5.0g Object at 11000 g's

[Paulbird20]

Force required to accelerate 5.0g object at 11000 g's. (in a centrifuge)
But it does not give me rpm or diameter so how can i calculate the force?

Im assuming it really doesn't matter that its in a centrifuge? Any leads would help

Write down the equation of force using Newton 2. What is the value of the centripetal acceleration?

 

[Paulbird20]

F= M* A

I tried converting the acceleration out of G's by dividing 11000 by 9.8 then times it by 5... Do i need to convert the mass out of grams and into KG?

A "G" is shorthand for the acceleration of gravity, 1 G is 9.8m/s^2 acceleration. You've got 11000 G's...you should be multiplying, not dividing. And yes, if you want your answer in the basic SI force unit of Newtons, mass must be expressed in kilograms.

Awsome i got it. Thank you so much phanthom jay i was dividing the 11000/ 9.8 rather than multiplying ;)
