Question
Two forces each of 10 N act on a body one towards north and the other towards east. The magnitude and direction of the resultant force is:
Correct Answer
Option D is the correct answer.
Detailed Explanation
Resultant magnitude = √(10² + 10²) = √200 = 10√2 N. Direction = tan⁻¹(10/10) = 45° from east toward north, i.e., 45° north of east.
Hint
Use vector addition for perpendicular forces.
