Homework Statement
The maximum speed with which a car can take a circular turn of radius R is v. The maximum speed with which the same car, under the same conditions, can take a circular turn of radius 2R is
A. 2v
B. v√2
C. 4v
D. 2v√2
Homework Equations
v = (2πr)/T
The Attempt at a Solution
Since radius is directly proportional to the velocity, wouldn't the answer just be A. 2v because doubling the radius would double the velocity? The correct answer is B. and I have no idea as to why. Could someone please explain why. Thank you
