Question

Assertion : The `upsilon-t` graph perpendicular to time axis is not possible in particle.
Reason : Infinite acceleration cannot be realised in particle.
A. If both Assertion and Reason are correct and Reason is the correct explanation of assertion.
B. If both Assertion and Reason are correct but Reason in not the correct explanation of Assertion.
C. If Assertion is true but Reason is false.
D. If Assertion is false but Reason is true.

Answer 1

Correct Answer - A
`a=(d upsilon)/(dt)` = slope of `upsilon - t` graph.
Perpendicular to t-axis, slope `= oo therefore a = oo`
