Question

What is the tension in a wire supporting a 1250-N camera submerged in water? The volume of the camera is 16.5x10^-3 m^3.

Answer 1

Tension in the wire supporting the camera after submerging in water is 1088 N

Step-by-step explanation:

As we know that the tension in the wire is balanced by the weight of camera and buoyancy force due to fluid

Here we know that the Buoyancy force due to fluid is upthrust due to liquid which act opposite to the weight

So force balance equation is given as

`T = W - F_b`

here we have

`W = 1250 N`

also we have

`F_b = \rho V g`

`F_b = (16.5 * 10^(-3))(1000)(9.81)`

`F_b = 162 N`

now we have

`T = 1250 - 162`

`T = 1088 N`
