An object is placed at a distance of 50 cms from a convex lens of focal length 20cms then find the nature and position of the image?

Since the object is placed beyond the focal length of the convex lens (50 cm > 20 cm), the image will be real, inverted, and formed between the focal point and twice the focal length on the opposite side of the lens. The position of the image can be calculated using the lens formula: 1/f = 1/v - 1/u, where f is the focal length of the lens, v is the image distance, and u is the object distance.
