    Hello,

    I am stuck on question 3 of the June 05 M1 paper (edexcel).

    Here is the paper:
    http://www.freeexampapers.com/FreeEx...IwMDUtMDYucGRm

    It asks to calculate tension in the string however there are two parts to the string... I cant understand which part to calculate... I have read the markscheme which says both tensions are equal however I cannot understand why :confused: ... Could someone please take a look at the question and explain this to me and perhaps tell me how they would go about solving the question (both parts (a) and (b))

    Many thanks in advance

    using tan a = opp/adj you know that BC = 4 and AB= 3

    The tension in both parts of the string is the same, so just resolve horizontally, or vertically and re-arrange to find T.

    It is a bead so is free to move along the string.
    A bead that can move along a string always rests in a positon so that the tension is the same in both parts of the string.

    If it was at a fixed position on the string, the tensions wouldn't necessarily be equal.
