Question

Topic :- Motion In plane

Need a answer with explaination!​

Answer 1

Explanation:

Answer :-

3) same in all groove.

solution:-

Time to fall =

$\sqrt \times \frac{2 \times 2r \cosΘ }{9 \cos Θ}$

So it is not depends on Θ i.e

the chord position

Answer 2

Answer : Option (C) - Same in all groove.

${\pmb{\underline{\sf{Required \: Solution....}}}}$

$\cos θ = \frac{R}{x} \\ \cosθ = \frac{length }{2R} \\ L = 2R \cosθ$

__________________________________

$: \implies S = ut + \frac{1}{2} at {}^{2} \\ : \implies \: S = \frac{1}{2} at {}^{2} \\ : \implies \: t = \sqrt{ \frac{2s}{a} } \\ : \implies \: t = \sqrt{ \frac{2R \cosθ \times 2}{g \cos θ } } \\ \implies \boxed{t = \sqrt{ \frac{4R}{g} } }$

${\pmb{\underline{\sf{Time \: is \: not \: Depending \: on \: θ \: }}}}$
