The two persons of masses 55 kg and 65 kg respectively, are at at opposite ends of a boat. The length of the boat is 30 m and weight 100 kg. The 55 kg man walkup to the 65 kg man and its with him. If the boat is in still water the centre of mass of the system shifts by

View answer and explanation

Correct option: C

Zero

Option C (Zero) is correct because, in the absence of external forces, the center of mass of the system (persons + boat) remains unchanged.
