Explanation
Resolving forces using vector addition
Steps:
- Identify the directions and magnitudes of forces X and Y from the diagram.
- Resolve each force into horizontal and vertical components using trigonometry.
- Sum the horizontal components and sum the vertical components separately.
- Find the resultant by combining the net horizontal and vertical components via Pythagoras theorem.
Why C is correct:
- Option C matches the resultant force direction and magnitude calculated from vector addition law, where forces add head-to-tail.
Why the others are wrong:
- A ignores the vector nature, treating forces as scalars.
- B misapplies the angle for component resolution.
- D confuses resultant with equilibrium condition.
Not enough information to specify exact values without diagram details.
Final answer: C
