Question

In which of the following cases, a force is not being applied?

• A. A man standing behind a stationary car.
• B. A car being pushed by a man.
• C. A man trying to stop a sliding car.
• D. A man standing on a car.

Answer 1

Answer: (A)

A man standing behind a stationary car.

For pushing a car, a force is required in the direction of motion of the car.

In trying to stop a sliding car, a force is required against the direction of motion of the car.

A man standing on the car applies the force of weight on the car.

But, to stand behind a stationary car, no net force needs to be applied on the car.
