1.	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
Answer» `(2(u_1-u_2))/((BETA - ALPHA)^2) (u_1 beta - u_2 alpha)` `(2(u_1-u_2))/(beta + alpha) (u_1 alpha - u_2 beta)` `(2(u_1-u_2)^2)/((beta - alpha)^2)` `(2u_1u_2)/(beta alpha)` ANSWER :A
