Two cars of mass ` m_(1) and m_(2) ` are moving in circle of radii `r_(1) and r_(2) ` , respectively . Their speeds are such that they make complete circles in the same time `t` . The ratio of their centripetal acceleration is :A. ` m_(1) r_(1) : m_(2) r(2)`B. `m_(1) : m_(2)`C. ` r_(1) : r_(2)`D. ` 1:1` |

Answer» Correct Answer - C ` a = r w^(2) = r xx((2 pi)/(t))^(2))` `:. (a_(1))/(a_(2)) = (r_(1))/(r_(2))` [ `:. T` is same ] |
