magnification produced (m) =

 \frac{ - v}{u} = \frac{1}{6} \\ where \: v = image \: distance(from \: pole \:of \: mirror) \\ \: \: \: \: \: \: \: \: \: \: \: \: \: u = object \: distance \\ therefore \\ v = \frac{ - u}{6} \\ f = - 6cm \\ using \: mirror \: formula \\ \frac{1}{v} + \frac{1}{u} = \frac{1}{f} \\ \frac{ - 6}{u} + \frac{1}{u} = \frac{ - 1}{6} \\ \frac{ - 5}{u} = \frac{ - 1}{6} \\ u = 30cm\\mark\:it\:as\:brainliest\:if\:u\:find\:it\:helpful
