Two forces while acting on a particle in opposite direc- tions, have the resultant of ION. If they act at right angles to each other, the resultant is found to be 50 N. Find the two forces

Answer»

Again when the forces are acting at right angles we have : SQUARED root(X^2 + Y^2 +2*X*Y*COS90) =50 NEWTON. THEREFORE, X=(10+Y)=10+30=40 Newton. HENCE the two forces are 30 and 40 Newton
