Solve the given problem:
An object of height \(3\) \(cm\) is placed at \(20\) \(cm\) from a concave lens of focal length \(20\) \(cm\). Find the size of the image.
\(u\) \(=\) \(cm\)
\(h\) \(=\) \(cm\)
\(f\) \(=\) \(cm\)
Apply the known values in the lens formula,
Thus, the image distance \(v\) is \(cm\)
