hope it helps

pls mark brainliest❤

Answer 2

$\huge {\red{\boxed{ \overline{\underline{ \mid\mathfrak{An}{\mathrm{sw}{ \sf{er}} \colon\mid}}}}}}$

____________________________

➠ Given

Magnification produced (m) = -1

Distance from the mirror of Image (v) = - 50 cm

_____________________________

➠ To Find

We have to find that,

Type of the mirror

Distance of the image from the object.

_____________________________

➠ Solution

Negative magnification means that image is real and inverted.

We know that concave mirror always have real and inverted image.

∴ Concave mirror is answer.

$\rule{200}{2}$

Now,

$\Large{\star{\boxed{\sf{m = \frac{-v}{u}}}}}$

$\sf{\implies -1 = \frac{\cancel{-}(\cancel{-}50)}{u}} \\ \\ \sf{\implies \frac{-1}{50} = \frac{1}{u}} \\ \\ \sf{\implies -50 \: cm = u}$
