This question has Statement-I and Statement-II. Of thefour choices given after the Statements, choose the one that best describes the two Statements. Statement-I: A point particle of mass in moving with speed v collides with stationary point particle of mass M. If the maximum energy loss possible is given asf(1/2mv^2) then f=(m/(M+m))Statement-II : Maximum enegy loss occurs when the particles get stuck together as a result of the collision. |

Answer» Statement-I is true, Statement-II is true, Statement-II is not a CORRECT explanation of Statement KE in COM frame is `1/2((Mm)/(M+m))V_(rel)^2` `KE_i=1/2((Mm)/(M+m))V^2``KE-f=0(because V_(rel)=0)` Hence loss in energy is `1/2((Mm)/(M+m))V^2` `:. implies f=(M)/(M+m)` and not `((m)/(M+m))` as given in statement_I`. |
