Question

Forces f1 and f2 act on a point mass in two mutually perpendicular directions the resultant force on the point mass will be

Answer 1

when the 2 forces is at perpendicular direction then the resultant force will be held in middle means at the inclined angle of 45 to each x and y axis and the formula was R =(A^2+B^2+2AB)^1/2 AND DIRECTION IS TAN(theta ) is equal to A ×SINTHETA /B+ACOSTHETA2
