Question

A virtual, erect and magnified image is formed between $F_1$ and $2F_1$ of a convex lens. The position of object should be

• A. between $F_1$ and $2F_1$
• B. between optical centre and $F_1$
• C. between $-\infty$ and $2F_1$
• D. at $F_1$

Answer 1

The correct option is B between optical centre and $F_1$

Convex lens forms a virtual, erect and enlarged image between $F_1$ and $2F_1$, when an object is placed between focus $F_1$ and optical centre $\left(O\right)$ as shown in figure.


So, the correct answer is option $\left(b\right)$.
