I can't seem to post pictures, but I will give the link to the question along with the link to the answer given in the mark scheme. Here goes:
Question: http://papers.xtremepapers.com/CIE/Cambridge%20International%20A%20and%20AS%20Level/Physics%20(9702)/9702_w07_qp_4.pdf
Answer link (mark scheme): http://papers.xtremepapers.com/CIE/Cambridge%20International%20A%20and%20AS%20Level/Physics%20(9702)/9702_w07_ms_4.pdf
The part I am having a problem with is the last part of the question. The mark scheme states that the force in cord = weight + centripetal force. I don't get why and how this is so because aren't the directions of the weight and the centripetal force opposite?
Thanks in advance, guys !
