Two cars start in a race with velocities `u_(1)` and `u_(2)` and travel in a straight line with acceleration 'a' and b .If both reach the finish line at the same time,the range of the race is

Options

A. `(2(u_1 - u_2))/((beta - alpha)^2) (u_1 beta - u_2 alpha)`
B. `(2(u_1 - u_2))/(beta + alpha) (u_1 alpha - u_2 beta)`
C. `(2(u_1 - u_2)^2)/((beta - alpha)^2) `
D. `(2 u_1 u_2)/(beta alpha)`

Answer

A
