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
- AIf both assertion and reason are true and reason is the correct explanation of assertion.
- BIf both assertion and reason are true but reason is not the correct explanation of assertion.
- CIf assertion is true but reason is false.
- 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.
