Let A be the last digit and let B be the second to last digit of your 8-digit student ID. (Example: or 20245347, A-7 and B-4.) A 4.50 cm tall object is placed at a distance of (16.8 A) cm from a convex lens with a focal length of (5.25+B) cm. Find the size of the resulting image Give your answer in centimeters (cm) with the correct sign and with 3 significant figures. Do NOT change the title line of your response. Do NOT post your work, just your answer. Your answer with unit must be the very first characters of your reply. If your answer is later marked Substantive', it is correct.

Explanation / Answer

ho = 4.50 cm

p = 17.8 cm

f = 6.25 cm

Applying lens formula,

1/f = 1/p + 1/q

1/6.25 = 1/17.8 + 1/q

q = 9.63 cm

m = - q / p = hi / ho

- 9.63 / 17.8 = hi / 4.50

hi = - 2.43 cm ........Ans
