Question

Statement I : If two particles, moving with constant velocities are to meet, the relative velocity must be along the line joining the two particles.
Statement II : Relative velocity means motion of one particle as viewed from the other.

• A. If both Statement I and Statement II are true and the Statement II is correct explanation of the Statement I
• B. If both Statement I and Statement II are true but the Statement II is not the correct explanation of the Statement II
• C. If Statement I is true but Statement II is false
• D. If statement I is false but statement II is true

Answer 1

Answer: (A)

Suppose motion of $1$ is viewed from $2$ then as $2$ is stationary. If $1$ is to meet it, it $1$ must come straight towards $2$ i.e., the relative velocity must be along $1-2$.
