Two men ' \( A \) ' and ' \( B \) ' are standing on a plank. ' \( B \) ' is at the middle of the plank and ' \( A \) ' is at the left end of the plank. Bottom surface of the plank is smooth. System is initially at rest and masses are as shown in figure. ' \( A \) ' and 'B' start moving such that the position of ' \( B \) ' remains fixed with respect to ground and ' \( A \) ' meets ' \( B \) '. Then the point where \( A \) meets \( B \) is located at :
(A) the middle of the plank
(B) \( 30 \mathrm{~cm} \) from the left end of the plank
