Answer:

Given: R = 3 m, f = 3/2 m, u = - 5 m, v = ?

Using mirror formula

(1/ f) = (1 / v) + (1 / u)

(2 / 3 ) = (1 / v) + (- 1 / 5)

(1 / v) = (2 / 3 ) + (1 / 5) = 13 / 15

v = (15 / 13) m

magnification, m = - (v / u) =  (15 / 13 x 5) = (3 / 13) m

since m = h' / h = 3 / 13

h' = (3 h / 13)

The image will be virtual, erect and diminished.
