A car is moving with a constant speed of $\displaystyle 20 \mathrm{~m} / \mathrm{s}$ in a circular horizontal track of radius $\displaystyle 40$ m . A bob is suspended from the roof of the car by a massless string . The angle made by the string with the vertical will be : (Take $\displaystyle \mathrm{g}=10 \mathrm{~m} / \mathrm{s}^2$ )
Official answer
