The radius for the inside of a curve is half the radius for the outside. With 2 cars of equal mass, car A travels on the inside and car B travels on the outside at equal speed. Which statement is correct?
a. The force on A is half the force on B
b. The force on B is half the force on A
c. A 4 times of B
d. B 4 times of A
Fc = m*v2/R
v = 2piR/T
The Attempt at a Solution
I substituted 2piR/T into v2 in the centripetal force equation, and then got
Fc = m*4pi2R/T2
So since the inside radius of half of the outside, the force on A should be half of that on B, which is answer a.
But the answer is apparently b.
But doesn't the equation show that it should be a?
