an object with mass 'm' is moving in a circle of radius 'R' at a constant speed of 'v.' The net force acting on the object must be increased if _. List all that apply
a.Its speed were increased (while 'R' and 'm' are held constant)
b.Its speed were decreased (while 'R' and 'm' are held constant)
c.Its radius were increased (while 'v' and 'm' are held constant)
d.Its radius were decreased (while v'' and 'm' are held constant)
e.Its mass were increased (while 'R' and 'v' are held constant)
d.Its mass were decreased (while 'R' and 'v' are held constant
e.none, none of these affect the net force

Best ResponseYou've already chosen the best response.0Imma go. The dummy variables thing: just sub in values and see what happens.

Best ResponseYou've already chosen the best response.1The magnitude of the force is F = mv^2/r Hence F goes up if  mass m goes up  velocity v goes up  radius r goes down
