The resultant of two forces P and Q is R. If Q is doubled, the new resultant is perpendicular to P. Then,
A P = R
B Q = R
C P = Q
D None of the above is correct
The resultant of the two forces ‘P’ and ‘Q’ is ‘R’. If ‘Q’ is doubled, the new resultant is perpendicular to ‘P’. Then
A P = Q
B Q = R
C Q = 2R
D None of these
