There is a small scratch on a disco record located 14.8 cm from the center. When played, the scratch makes the record skip 30 times each minute (i. e., the scratch passes under the record player needle 30 times per minute). What is the linear speed of the scratch as it turns

< coa = 150 ( given)

as ba and bc are tangents

so oc and oa is perpendicular to cb and ab respectively because in circle normal passes through centre

so in quadrilateral oabc

< coa + < oab + < ocb + < abc = 360

150 +90+90 + < abc = 360

330 + < abc = 360

< abc = 360 -330 = 30

so < abc = 30
