Two forces A and B have a resultant . If B is doubled, the new resultant is perpendicular to A. Then
Two forces are such that the sum of their magnitudes is 18 N and their resultant is perpendicular to the smaller force and magnitude of resultant is 12 N. Then the magnitudes of the forces are
1. 12 N, 6 N
2. 13 N, 5N
3. 10 N, 8 N
4. 16 N, 2 N
