NEET2019PhysicsMotion in One DimensionActual

Assertion : The relative velocity between any two bodies may be equal to sum of the velocities of two bodies. Reason : Sometimes, relative velocity between two bodies may be equal to difference in velocities of the two.

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

When the bodies are moving in same direction, relative velocity between them is equal to the differences in velocities of two bodies. When two bodies are moving in opposite directions, relative velocity between them is equal to the sum of the velocities of two bodies.
