A wire of length 10 cm is gently placed horizontally on the surface of water having a surface tension of `75xx10^(-3)` N/m . What is the force required to pull up the wire from the surface .

A uniform wire of length 20 cm is bent into a circle, It is placed gently on the surface of water of surface tension 0.07Nm^(-1) . The extra force than its weight required to pull it out of the water is

A ring of radius 0.75 cm is floating on the surface of water . If surface tension of water is 0.07N//m , then the force required to lift the ring from the surface of water will be

A ring of radius 0.75 cm is floating on the surface of water . If surface tension of water is 0.07N//m , then the force required to lift the ring from the surface of water will be

A ring of radius 0.75 cm is floating on the surface of water . If surface tension of water is 0.07 N/m the force required to lift the ring from the surface of water will be

A straight piece of wire 5 cm long is placed horizontally on the surface of water and gently pulled up. It is found that a force of 7 xx 10^(-3) N in addition to weight of wire is required for that purpose. The surface tension of water is

A wire 0.1m long is placed horizontally on the surface of water and is gently pulled up with a force of 1.456 xx 10^(-2) N to keep the wire in equilibrium. Calculate the surface tension of water.

A light wire 10 cm long is placed horizontally on the surface of water and is gentely pulled up with a force of 1.456xx10^(-2)N to keep the wire in equilibrium. What is the surface tension of water ?

A small piece of wire of length 4 cm is floating on the surface of water. If a force of 560 dynes in excess of itss apparent weight is requried to pull it up from the surface find the surface tension of water.
