While teaching the topic ‘Friction’ to Class V students, a teacher gave a number of examples to explain that friction is also useful to us in many ways. Which one of the following examples was quoted by her incorrectly?

Correct option is B

The correct answer is An object thrown vertically upwards always comes back to us due to friction.
When a ball is thrown vertically upward, its velocity decreases gradually. This is because the earth produces a gravitational force that brings down everything that goes up. Friction is not applied in this situation.
