Hello p75213

Welcome to Math Help Forum!If a force acts outwards from the origin along a line that makes a direction measured anticlockwise from the positive direction of , then its components along and areand , respectivelySince the angles are measured from the direction of , I assume they are all in the same sense (e.g. all anticlockwise). So we can write down the components along and perpendicular to , where is the ring, as follows:

Along :Perpendicular to :

We find the resultant force by summing these components:

Along ON:The magnitude of the resultant is therefore .

Perpendicular to ON:
