A body projected along an inclined plane of angle of inclination 300 stops after covering a distance x_(1). The same body projected with the same speed stops after covering a distance x_(2) when the angle of inclination of the inclined plane is increased to 60^(@) the ratio of x_(1)//lx_(2) is |

Answer» `sqrt(2)` In first case`0-u^(2)=2(-gsin30^@)x_(1)` or `u^(2)=gx_(1)` In SECOND case`0-u^(2)=2(-gsin60^@)x_(2)` or `u^(2)=sqrt(3)gx_(2)` or `gx_(1)=sqrt(3)gx_(2)` or `x_(1)/x_(2)=sqrt(3)` |
