Question

For ordinary terrestrial experiments, the observer in an inertial frame in the following cases is

• A. A child revolving in a-giant wheel
• B. A driver in a sports car moving with a . constant high speed of $200{kmh}^{-1}$ on a straight road
• C. The pilot of an aeroplane which is taking off
• D. A cyclist negotiating a-sharp curve

Answer 1

Answer: (B)

A driver in a sports car moving with a . constant high speed of $200{kmh}^{-1}$ on a straight road

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.
