Hi,

Initially,

the forces acting on the body would be gravity and buoyancy in the opposite directions. find the net force on the body and find the acceleration.

The forces acting will be buoyant force and weight so W-F=MA. NowF=boyant force=dVg Where v=volumeAlso,W=mgNow,-dvg+mg=ma......(1)We know that mass is density*volume so M=PV Putting in(1)Pvg-dvg=ma(P-d)VG=maVolume is mass/density(m/p)(p-d)mg/p=ma So a is (p-d)g/p=aThank u
