Question 1241

jamb 1978

A solid suspended by a piece of string is completely immersed in water. On attempting to lift the solid out of the water, the string breaks when the solid is partly out of the water. This is because

Athe tension in the string decreases as the solid is lifted

Bthe mass of the solid has increased

Cthe solid apparently weighs less when completely immersed in water than when partially immersed

Dpart of the solid still in water is exerting more force on the string

Ethe solid is no longer in equilibrium with water

Question 1242

jamb 1978

The density of a solid is defined as the

Amass of the solid compared to the mass of an equal volume of water

Bamount of water displaced when a unit mass of thesolid is immersed in it

Cweight per unit volume of the solid

Dvolume per unit mass of the solid

Emass per unit volume of the solid
