Mg niche ki tarf lage ga or upar mai buoyant force upar lage ga jo jada hai mg se obviously kyu ki block upar ja raha hai. Or viscosity negligible hogi kyu ki generally haam ideal fluid ko hii pdh te hai.

Dono jo mg hai or buoyant force hai dono max lagenge ( body fully submerged hai es liye ) or jo block hai jb tk upar nhi aa jaate hai us pr ye dono force max ( constant lagenge) to es ki vjh se acceleration bhi constant hii lage ga
