-- 8. Two car of masses m1 and m2 are moving in circles of radii r1 and r2 respectively. Their speeds are such that they make complete circle in the same time t. The ratio of their centripetal acceleration is
A
m1r1 : m2r2
B
m1 : m2
C
r1 : r2
D
1 : 1
Explanation
Centripetal acceleration a = ω²r. Since time period T is same, angular velocity ω = 2π/T is same for both. Ratio a1/a2 = (ω²r1) / (ω²r2) = r1/r2.
