Give the value of the velocity at which they are meeting
State whether true or false. If false, correct the statement.
Distance covered by a particle never becomes zero but displacement becomes zero.
Assertion: Displacement of a body may be zero when distance travelled by it is not zero.
Reason: The displacement is the shortest distance between initial and final position.
