Question

The resultant of two forces P and Q is R. If Q is doubled, the new resultant is perpendicular to P. prove Q=R? [ do this question by triangle law ]

Answer 1

The resultant of 2 vectors P and Q is R. If Q is doubled, then the new resultant is perpendicular to P. What is the value of R? The resultant of two forces P and Q is R. If Q is doubled, R is doubled. ... The resultant of two forces p and q is perpendicular to p, then what is the angle between the forces?
