What condition on the resultant force allows constant velocity?
A
The resultant force is zero.
B
On a plane inclined at θ\thetaθ, weight has component mgsinθ\boxed{mg\sin\theta}mgsinθ down the plane and component mgcosθmg\cos\thetamgcosθ into the plane.
C
It has reached its limiting value, F=μRF=\mu RF=μR.
D
When there are no other perpendicular force components or acceleration.
