Question

You spill a bucket of soapy water on a marble floor accidentally. Which of the following statement is correct?

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

Answer 1

The correct option is D

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

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