Answer 1

The correct answer is Force/Length.

In News

Surface tension is a physical property of liquids that makes them acquire the least surface area possible.

Key Points

Surface tension is defined as the force per unit length acting on the surface of a liquid.
The correct formula for surface tension is Force/Length, representing the force acting along the surface of the liquid divided by the length over which it acts.
It is typically measured in units of Newton per meter (N/m).
Surface tension plays a crucial role in various natural phenomena, such as the formation of droplets and the behavior of insects that walk on water.

Additional Information

Important Terminologies:
- Surface Tension: A measure of the elastic tendency of a fluid surface which makes it acquire the least surface area possible. It is caused by the attraction between the molecules of the liquid.
- Force: An interaction that, when unopposed, changes the motion of an object. It is a vector quantity having both magnitude and direction.
- Length: The measurement or extent of something from end to end; the greater of two or the greatest of three dimensions of an object.
- Newton (N): The International System of Units (SI) derived unit of force. It is named after Isaac Newton in recognition of his work on classical mechanics.
