a) the position of the image
b) focal length of the concave mirror

Answer 1

Answer:

with magnification formula we can obtain the distance of image . with that value we can find focal length by using mirror formula . with the help of focal length we can calculate the position of image .

Answer 2

Answer:

a) Image- distance, v = -10 cm

b) Focal length, f = -6 cm
