If the bend is 20 cm from the pole of the mirror,then the ratio of the lengths of the images of the upright and horizontal portions of the wire isMEDIUMShareStudy laterANSWERGiven, u=−20 ; f=−5From mirror formula, v1 + U1 = f1 v1 − 201 = 5−1 v= 3−20 magnification= u−v = 3−1 lateral magnification is (u−f) 2 f 2 = (20−5) 2 25 = 91 Ratio of up-right portion to lateral portion is 91 31 =3:1option B is correct Explanation:HERE IS YOUR ANSWER PLEASE MARK ME BRAINLIEST
