TS EAMCET 2022 (Online) 20th July Evening Shift | Circular Motion Question 10 | Physics

A cyclist is riding with a speed of $36 \mathrm{~km} / \mathrm{h}$. As he approaches a circular turn on the road of radius 50 m , he applies brakes and reduces his speed at the constant rate of $0.5 \mathrm{~m} / \mathrm{s}$ every second. The magnitude and direction of the net acceleration of the cyclist on the circular turn respectively, are

$\frac{\sqrt{3}}{2} \mathrm{~ms}^{-2}, \tan ^{-1}(4)$

$\frac{\sqrt{3}}{2} \mathrm{~ms}^{-2}, \tan ^{-1}\left(\frac{1}{4}\right)$

$\sqrt{17} \mathrm{~ms}^{-2}, \tan ^{-1}\left(\frac{1}{4}\right)$

$\frac{\sqrt{17}}{2} \mathrm{~ms}^{-2}, \tan ^{-1}(4)$
