21yeh!! ho gaya..... easy tha re.........
BTW Q2 ka kuch karo naaaaaa
1well, here is my solution... see if it helps...!!!
\frac{\partial x}{\partial t} = \frac{\sqrt{k-x^{2}}}{\sqrt{k'}}
integrating d above equation implies
\sin^{-1}\frac{\sqrt{k}}{x} = \frac{t}{\sqrt{k'}}
x = \sqrt{k}.cosec\frac{t}{\sqrt{k'}}
hence the time period = 2Π√k'...
21YOUr Ans is Perfect but I didnt get ur First step only .... [2]
1just try to isolate 'v' from d given equation... and put v = dx/dt ... and then integrate... it'll b done... [1]
