Answer 1

hey dear ur answer is ...♥♥♥
Here →_→
1/v +1/ u = 1/f
1/v===== 1/f -1/u
1/15 -1/10 === 1.9

Answer 2

${\purple{\boxed{\large{\bold{Given}}}}}$

$\:\sf\underline\blue{u\:=\:-10cm}\:$

$\:\sf\underline\red{r\:=\:-15cm}\:$

$\:\sf\underline\orange{f\:=\:-\dfrac{15}{2}cm}\:$

${\green{\boxed{\large{\bold{Solution}}}}}$

$\huge{\orange{\underline{\red{\mathscr{We\: know}}}}}$

${\green{\boxed{\large{\bold{ \dfrac{1}{f} = \dfrac{1}{u} + \dfrac{1}{v}}}}}}$

${⟹ \dfrac{-2}{15} = \dfrac{1}{-10} + \dfrac{1}{v}}$

${⟹ \dfrac{-2}{15} + \dfrac{1}{-10} = \dfrac{1}{v}}$

${⟹ \dfrac{-4+3}{30} = \dfrac{1}{v}}$

${⟹ \dfrac{-1}{30}\:=\:\dfrac{-1}{v}}$
