Problem

Optic axis of a thin equiconvex lens is the x-axis. The coordinates of a point object and its image are

(-40 \text{ cm}, 1 \text{ cm})

and

(50 \text{ cm}, -2 \text{ cm})

respectively. Lens is located at (a)

x = +20 \text{ cm}

(b)

x = -30 \text{ cm}

(c)

x = -10 \text{ cm}

(d) origin
