Use the mirror equation 1/f = 1/do + 1/di. For a concave mirror f = +5.0 cm and di = −10.0 cm (virtual image), so
1/do = 1/f − 1/di = 1/5 − (−1/10) = 1/5 + 1/10 = 3/10.
Thus do = 10/3 ≈ 3.33 cm, rounded to the nearest whole centimeter: 3 cm.
1/do = 1/f − 1/di = 1/5 − (−1/10) = 1/5 + 1/10 = 3/10.
Thus do = 10/3 ≈ 3.33 cm, rounded to the nearest whole centimeter: 3 cm.
