Explanation / Answer

-1/28 + 1/v = -2/14

so v = -9.33 cm

b) m = 9.33/28 = I/O

so I = 2 mm

c) -1/14 + 1/v = -2/14

v = -14 cm

d) m = 14/14= 1 so I = O = 6 mm

e) -1/3.5 + 1/v = -2/14

v = 7 cm

f) m = 7/3.5 = 2 = I/O

so I = 2x6 = 12mm

g) -1/10 + 1/v = -2/14

so v = -23.33

h) m = 23.33/10 = I/O

so I = 2.33 x 6 = 14 mm
