hey..
the object should be placed at a distance of less than 10cm
An erect image is only formed by a concave mirror when object is placed between pole and focus..
R = 2F
20 = 2F
F = 20/2
F = 10cm
the object should be placed at a distance of less than 10cm

ok bro....when an object is placed at centre of curvature the image is formed on itself and the distance between pole and COC is called Radius of curvatures which is 20cms given by you..so when an object is placed between pole and focus then the image will be erect so to find Focus we have a relationship R = 2F 20 = 2F F = 10 cm so the object should be placed at less than 10cms to get an erect image
