Question

Find the tension in the cable at its lower end, where it is attached to the diver

• A. $230N$
• B. $200N$
• C. $120N$
• D. $400N$

Answer 1

The correct option is D $400N$

Weight of diver with suit $F=120\times 10=1200N$
Buoyancy force acting upward $B=\rho Vg=\left(1000\right)\left(0.08\right)\left(10\right)=800N$
Tension in the wire $T=F-B$
$T=1200-800=400N$
