NEET2018PhysicsMotion in One DimensionActual

Assertion : For a given time interval, average velocity is single valued while average speed can have many values. Reason : Velocity is a vector quantity and speed is a scalar quantity.

Options

  1. AIf both assertion and reason are true and reason is the correct explanation of assertion.
  2. BIf both assertion and reason are true but reason is not the correct explanation of assertion.
  3. CIf assertion is true but reason is false.
  4. DIf both assertion and reason are false.

Correct answer

B. If both assertion and reason are true but reason is not the correct explanation of assertion.

Step-by-step solution

For a given interval of time, the body in motion may go from one position to another through different paths, where displacement in a given time has one value but distance travelled can have many values. Due to which, assertion is correct. The reason is also correct but not a true explanation of assertion.
