Unformatted text preview: unknown object to be 23.6g. To help us find the percent of error, we used the formula: (vector (A+B) angle)(vector C angle) x 100 360 ° The relationship between A, B, and C is that they should add up to 0 for equilibrium. To find the percent error, you must find the magnitude of vectors A and B. The X components are 55sin45+55sin300 and the Y components are 55cos45+55cos300. You put the y/x and find the tan1 of that number. You get the value of 25%, after subtracting the vector angle C and adding the vectors, then dividing by 360 and then multiplying by 100. Error in this experiment may have came from the string connecting the hangers to the point in middle may have been off target making the angles wrong. Then there may also be the error that the point was not exactly in the middle and was still a minor bit off that we would not be able to calculate because it may be smaller then our smallest weights....
