Given below are two statements. One is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A) : Three identical spheres of same mass undergo one dimensional motion as shown in figure with initial velocities v_ A =5 ~m / s , v_ B =2 ~m / s , v_ C =4 ~m / s . If we wait sufficiently long for elastic collision to happen, then v_ A =4 ~m / s , v_ B =2 ~m / s , v_ C =5 ~m / s will be the final ve

Options

  1. A(A) is false but (R) is true
  2. BBoth (A) and (R) are true but (R) is NOT the correct explanation of (A)
  3. CBoth (A) and (R) are true and (R) is the correct explanation of (A)
  4. D(A) is true but (R) is false
