MCQ
For ordinary terrestrial experiments, the observer in an inertial frame in the following cases is:
  • A
    A child revolving in a - giant wheel.
  • A driver in a sports car moving with a. constant high speed of $200kmh^{-1}$ on a straight road.
  • C
    The pilot of an aeroplane which is taking off.
  • D
    A cyclist negotiating a - sharp curve.

Answer

Correct option: B.
A driver in a sports car moving with a. constant high speed of $200kmh^{-1}$ on a straight road.
$b.$ A driver in a sports car moving with a. constant high speed of $200kmh^{-1}$ on a straight road.
Explanation:
$A$ and $D$ options experience centripetal acceleration. $C$ experience linear acceleration and a inertial frame $n =$ must be non $-$ accelerating.
$B$ is non $-$ accelerating hence correct answer.
