Problem
Two concurrent forces act at a point with an angle of 120∘ between them. One force has magnitude 6N, and their resultant has magnitude 10N.
(i) Formulate the mathematical relation that connects the unknown force B, the known force, and the resultant.
(ii) Calculate the magnitude of the unknown force B.
(iii) Find the angle that the resultant makes with the unknown force B. (Retain two significant figures.)
