To lift a wire ring of radius1.75 cm from the surface of a container of blood plasma, a vertical force of 1.61 × 10−2 N greater than the weight of the ring is required. Calculate the surface tension of blood plasma from this information.

To determine
The surface tension of blood plasma.

Explanation
The surface tension of blood plasma is γ=F/Ltotal=F/2(2πr) since the ring has two sides (inside and outside).

Given info: The vertical force on the ring is 1.61×102N and the radius of the ring is 1.75cm .

The formula for the surface tension of blood plasma is,

γ=F4πr

• F is the vertical force.
• r is radius of the ring.

Substitute 1.61×102N for F and 1.75cm for r to find γ
