A light string passing over a smooth light pulley connects two blocks of masses m_(1) and m_(2) (vertically). If the acceleration of the system is g//8, then the ratio of the masses is: |

Answer» 2N `(g)/(8)=((m_(1)-m_(2))/(m_(1)+m_(2)))g, (1)/(8)=(m_(1)-m_(2))/(m_(1)+m_(2))` `8m_(1)-8m_(2)=m_(1)+m_(2)` `7m_(1)=9m_(2)(m_(1))/(m_(2))=(9)/(7)` `m_(1):m_(2)::9:7` Hence choice is (b) |
