Answer 2

ANSWER✔

$\large\underline\bold{GIVEN,}$

$\sf\dashrightarrow r=10m$

$\sf\dashrightarrow v= 10m/s$

$\sf\therefore TAKING\:G=10m/s^2$

FROM GIVEN DIAGRAM,

WE GET,

$\sf\therefore Tcos \theta = m \times g\:---equation^1$

$\sf\therefore Tsin \theta= \dfrac{m \times v^2}{r}---equation^2$

✯TAKING THE GIVEN EQUATIONS,

$\sf\large\therefore on \:dividing\:them.\:we\:get,$

$\sf\implies tan \theta= \dfrac{m \times v^2}{r \times m \times g}$

$\sf\implies tan \theta= \dfrac{\cancel{m} \times v^2}{r \times \cancel{m} \times g}$

$\sf\implies tan \theta= \dfrac{v^2}{r \times g}$

$\sf\large\therefore NOW,$

$\sf\implies tan \theta= \dfrac{(10)^2}{10 \times 10}$

$\sf\implies tan \theta= \dfrac{10 \times 10}{10 \times 10}$

$\sf\implies tan \theta= \dfrac{\cancel{10 \times 10}}{\cancel{10 \times 10}}$

$\sf\implies tan \theta= 1$

$\sf\therefore tan45\degree=1$

$\sf\large\therefore \theta= 45 \degree$

$\large{\boxed{\bf{ \star \:\: \theta= 45 \degree \:\:\star}}}$

$\large\underline\bold{HENCE,OPTION \:'C':-45 \degree\: IS \:CORRECT }$
