A pencil is placed upright at a distance 10 cm from a convex lens of focal length 15 cm. The nature of the image of the pencil will be

real, inverted and magnified

real, erect and magnified

virtual, erect and reduced

virtual, erect and magnified

It is given that, Focal length of the convex lens, f = 15cm
Distance of pencil from the pole, u = − 10 cm
Applying mirror formula, we get

As magnification is positive and less than one image will be vertical, erect and diminished
