Answer 1

Answer #1

We have lens formula, 1/f = 1/u + 1/v

where, f is focal length = +10 cm,

u is object distance = 5 cm and

v is image distance = ?

therefore using lens formula, 1/10 = 1/5 + 1/v ==> 1/v = 1/10 - 1/5 = -1/10

==> v = -10 cm [Answer] Negative image distance indicates image is virtual that is on the same side of the lens as the object.

and magnification = image distance / object distance

==>magnification = -10/10 = -1 [Answer] Negative magnification indicates image is inverted.
