Question

Suppose you accidently spill soapy water on a marble floor. Which of the following statements is correct?

• A. It will be difficult to walk because the force of friction decreases.
• B. It will be easier to walk because the force of friction increases.
• C. It will be difficult to walk because the force of friction increases.
• D. It will be easier to walk because the force of friction decreases.

Answer 1

The correct option is A

It will be difficult to walk because the force of friction decreases.

In order to walk, we push the ground in backward direction with our feet. The force of friction pushes us in forward direction and allows us to walk. The force of friction between the ground and our feet decreases when there is soapy water on floor. Hence, it becomes difficult to walk.
