`ABC` is triangle, right angled at A. The resultant of the forces acting along `vec(AB). vec(AC)` with magnitudes `1/(AB)` and respectively is the force along `vec(AD),` where D is the foot of the perpendicular from A onto BC. The magnitude of the resultant is-

ABC is isosceles triangle, right angled at A. The resultant of the forces acting along vec(AB), vec(AC) with magnitudes 1/(AB) and 1/(AC) respectively is the force along vec(AD) , where D is the foot of the perpendicular from A on BC. The magnitude of the resultant is:
