JAMB - Physics (1980 - No. 23)
An object of mass m and volume v, is totally immersed in a liquid of density p. The tension of a string holding it is
mg
(m + pv)g
(m - pv)g
pvg
[M/m-pv]g
Selitys
Tension = upthrust on object
= weight in air - weight i liga
= mg - pvg
= (m - pv)g
= weight in air - weight i liga
= mg - pvg
= (m - pv)g
