MCQ
$Assertion$ : A body with constant acceleration always moves along a straight line.

$Reason$ : A body with constant acceleration may not speed up.

  • A
    If both Assertion and Reason are correct and the Reason is a correct explanation of the Assertion.
  • B
    If both Assertion and Reason are correct but Reason is not a correct explanation of the Assertion.
  • C
    If the Assertion is correct but Reason is incorrect.
  • ✓
    If the Assertion is incorrect but the Reason is correct.
✓

Answer

Correct option: D.
If the Assertion is incorrect but the Reason is correct.
d
In case of circular motion, constant acceleration creates circular motion. In circular motion (uniform) the body in motion does not speed up inspite of acceleration.
