The sum of magnitudes of two forces acting at a point is 18 and the magnitude of their resultant is 12 . If the resultant is at

90^{\circ}

with the force of smaller magnitude, then their magnitudes are

View answer and explanation

Correct option: C

5,13

Option C (5,13) is correct because these magnitudes satisfy the given conditions: their sum is 18, their resultant is 12, and the resultant is at 90 degrees with the smaller force.
