PhysicsSingle correct+4 / -1Question 28 of 75

A car moving with a speed of 54 km/h takes a turn of radius 20 m. A simple pendulum is suspended from the ceiling of the car. Determine the angle made by the string of the pendulum with the vertical during the turning. (Take $g=10$ m/s²)

\tan^{-1}(0.5)

\tan^{-1}(0.75)

\tan^{-1}(1.125)

\tan^{-1}(0.25)

Answer and worked solution

Official answer: C

Pendulum in the turning car. $\tan\theta=\dfrac{v^2}{rg}=\dfrac{15^2}{20\times10}=1.125$ .

(C)
