A raft of mass M=600 kg floats in calm water with 7 cm submerged. When a man stands on the raft, 8.4 cm are submerged, the man's mass is

30 kg

60 kg

90 kg

120 kg

Text Solution

Verified by Experts

The correct Answer is:

Upthrust on 7 cm = 600 kg
`therefore"Upthrust on further 1.4 cm"=600/7xx1.4=120 kg `
