Explanation / Answer

using the lens equation

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

1/v + 1/210 = 1/26

v = 29.67 mm

magnification = - (v/u) = - (29.67/210) = -0.141

b) 1/v + 1/210 = 1/105

v = 210 mm

magnification = -(v/u) =-(210/210) = -1

c) 1/v + 1/210 = 1/300

v = -700

magnification = -(v/u) = -(-700/210) = 3.33
