Question

A solid sphere of density n( <1) times lighter than water is suspended in a water tank by a string tied to its
base as shown in fig. If the mass of the sphere is m then the tension in the string is given by




.​

Answer 1

Answer:

Hello mate✌✌✌

Tension of spring T = upthrust

Weight of sphere = Vσg − Vρg

Tension = Vσg − Vηρg − Vρg (•°• σ = ηρ)

= (η - 1)V ρg

= (η - 1)mg

Hence, the tension in the string is given by :

(η - 1)mg

Hope it helps✌✌✌

Answer 2

Answer:

→ choose anwer (a) {(1-n)/n}(mg)

Explanation:

→ choose anwer (a) {(1-n)/n}(mg)
