Two persons of masses `55 kg` and `65 kg` respectively are at the opposite ends of a boat. The length of the boat is `3.0 m` and weights `100 kg`. The `55 kg` man walks up to the `65 kg` man and sits with him. If the boat is in still water the centre of mass of the system shifts by.

zero

0.75 m

3.0 m

2.3 m

Text Solution

Verified by Experts
