First off, are you trying to talk about a "centripetal" force?Originally Posted by cheesepie
Second, when you give the formula F = -mw(wXr) what are you trying to say? I'm guessing: .
Finally you said . What direction is the "2" in?

1) The centrifugal force acting on an object of mass m kg , with position vector r from the origin, and rotating at a constant angular velocity w radians per second is given by -mw(wXr) Newtons. calculate the centrifugal force vector and its magnitude for an object with m = 3kg,r=-2i+5j+7k metres and w=j+2 radians per sec
2) An electric charge of q1 coulomb, at a position vector r and moving velocity v1 produces a magnetic induction B given B =
m vXr
__ q [_____]
4pi lrlsquare
where m is the constant of permeability . The magnetic force F exerted on a second charge of q2 coulombs and moving with velocity v2 is given f=q2v2XB Find the magnetic force F if v1=i+j-k,v2=-3i+j,r=2i-j+3k and q1=q2=1
