Question-5 (doable)
A magnified, inverted image is located a distance of 38.0 cm from a converging lens with a focal
length of 10.0 cm. Determine the object distance and tell whether the image is real or virtual
[ 13.6 cm )

Answer 1

`\\ \rm\Rrightarrow (1)/(u)+(1)/(v)=(1)/(f)`

`\\ \rm\Rrightarrow (1)/(u)=(1)/(-10)+(1)/(38)`

`\\ \rm\Rrightarrow (1)/(u)=(-19+5)/(190)`

`\\ \rm\Rrightarrow (1)/(u)=(-14)/(190)`

`\\ \rm\Rrightarrow u=(190)/(-14)`

`\\ \rm\Rrightarrow u=13.6cm`

Real
